Time Travel in the Torah

This week’s parasha is Ki Tisa, in which we read of Moses’ return from Mt. Sinai where he had spent forty days with God. During that time, he had composed the first part of the Torah and received the Two Tablets. The Talmud (Menachot 29b) tells us of another incredible thing that happened:

…When Moses ascended on High, he found the Holy One, Blessed be He, sitting and tying crowns on the letters of the Torah. Moses said before God: “Master of the Universe, who is preventing You from giving the Torah [without these additions]?” God said to him: “There is a man who is destined to be born after many generations, and Akiva ben Yosef is his name. He is destined to derive from each and every tip of these crowns mounds upon mounds of halakhot.” [Moses] replied: “Master of the Universe, show him to me.” God said to him: “Return behind you.”

Moses went and sat at the end of the eighth row [in Rabbi Akiva’s classroom] and did not understand what they were saying. Moses’ strength waned, until [Rabbi Akiva] arrived at the discussion of one matter, and his students said to him: “My teacher, from where do you derive this?” [Rabbi Akiva] said to them: “It is an halakha transmitted to Moses from Sinai.” When Moses heard this, his mind was put at ease…

Up on Sinai, Moses saw a vision of God writing the Torah—this is how Moses himself composed the Torah, as he was shown what to inscribe by God—and he saw God adding the little tagim, the crowns that adorn certain Torah letters. Moses was puzzled by the crowns, and asked why there were necessary. God replied that in the future Rabbi Akiva would extract endless insights from these little crowns.

Moses then asked to see Rabbi Akiva, and was permitted to sit in on his class. Moses could not follow the discussion! In fact, the Talmud later says how Moses asked God: “You have such a great man, yet you choose to give the Torah through me?” At the end of the lesson, Rabbi Akiva’s students ask him where he got that particular law from, and he replied that it comes from Moses at Sinai. Moses was comforted to know that even what Rabbi Akiva would teach centuries later is based on the Torah that Moses would compose and deliver to Israel.

This amazing story is often told to affirm that all aspects of Torah, both Written and Oral, and those lessons extracted by the Sages and rabbis, stems from the Divine Revelation at Sinai, and from Moses’ own teachings. It is a central part of Judaism that everything is transmitted in a chain starting from Moses at Sinai, down through the prophets, to the Anshei Knesset HaGedolah, the “Men of the Great Assembly” and to earliest rabbis, all the way through to the present time.

What is usually not discussed about this story, though, is the deeper and far more perplexing notion that Moses travelled through time! The Talmud does not say that Moses saw a vision of Rabbi Akiva; it says that he literally went and sat in his classroom. He was there, sitting inconspicuously at the end of the eighth row. As a reminder, Moses received the Torah in the Hebrew year 2448 according to tradition, which is 3331 years ago. Rabbi Akiva, meanwhile, was killed during the Bar Kochva Revolt, 132-136 CE, less than 2000 years ago. How did Moses go 1400 years into the future?

Transcending Time and Space

In his commentary on Pirkei Avot (Magen Avot 5:21), Rabbi Shimon ben Tzemach Duran (1361-1444) explains:

Moshe Rabbeinu, peace be upon him, while standing on the mountain forty days and forty nights, from the great delight that he had learning Torah from the Mouth of the Great One, did not feel any movement, and time did not affect him at all.

As we read at the end of this week’s parasha, Moses “was there with God for forty days and forty nights; he ate no bread and drank no water, and He inscribed upon the tablets the words of the Covenant…” (Exodus 34:28) At Sinai, Moses had no need for any bodily functions. Rabbi Duran explains that from his Divine union with God, Moses transcended the physical realm. In such a God-like state, he was no longer subject to the limitations of time and space.

In this regard, Moses became like a photon of light. Modern physics has shown that light behaves in very strange ways, and does not appear to be subject to time and space. Fraser Cain of Universe Today explains how

From the perspective of a photon, there is no such thing as time. It’s emitted, and might exist for hundreds of trillions of years, but for the photon, there’s zero time elapsed between when it’s emitted and when it’s absorbed again. It doesn’t experience distance either.

Light transcends time and space. In this way, Moses was like light. And this is quite fitting, for this week’s parasha ends with the following (Exodus 34:29-33):

And it came to pass when Moses descended from Mount Sinai, and the Two Tablets of the Testimony were in Moses’ hand when he descended from the mountain, and Moses did not know that the skin of his face had become radiant while He had spoken with him. And Aaron and all the children of Israel saw Moses, and behold, the skin of his face had become radiant, and they were afraid to come near him… When Moses had finished speaking with them, he placed a covering over his face.

Moses glowed with a bright light, so much so that the people couldn’t look at him, and he would wear a mask over his face. Moses had become light. And light doesn’t experience time and space like we do. There is something divine about light. It therefore isn’t surprising that the Kabbalists referred to God as Or Ain Sof, “light without end”, an infinite light, or simply Ain Sof, the “Infinite One”. Beautifully, the gematria of Ain Sof (אין סוף) is 207, which is equal to light (אור)!

Travelling to the Future

While Moses was instantly teleported into the future, we currently have no scientifically viable way for doing so. However, the notion of travelling into the future is a regular fixture of modern science fiction, and the way it usually presents itself is through some form of “cryosleep”. This is when people are either frozen or placed into a state of deep sleep, or both, for a very long time (usually because they are flying to distant worlds many light years away), and are reanimated in the distant future. For this there is a good scientific foundation, as there are species of frogs in Siberia, for example, that are able to freeze themselves for the winter, and thaw in the spring. They can do this without compromising the integrity of their cellular structure, in a process not yet fully understood. If we could mimic this biological process, then humans, too, could potentially freeze themselves for long periods of time, “thawing” in the future. And this, too, has a precedent in the Talmud (Ta’anit 23a):

[Honi the Circle-Drawer] was throughout the whole of his life troubled about the meaning of the verse, “A song of ascents, when God brought back those that returned to Zion, we were like them that dream.” [Psalms 126:1] Is it possible for a man to dream continuously for seventy years? One day he was journeying on the road and he saw a man planting a carob tree. He asked him: “How long does it take [for this tree] to bear fruit?” The man replied: “Seventy years.” He then further asked him: “Are you certain that you will live another seventy years?” The man replied: “I found [ready-grown] carob trees in the world; as my forefathers planted these for me so I too plant these for my children.”

Honi sat down to have a meal and sleep overcame him. As he slept a rocky formation enclosed upon him which hid him from sight and he continued to sleep for seventy years. When he awoke he saw a man gathering the fruit of the carob tree and he asked him: “Are you the man who planted the tree?” The man replied: “I am his grandson.” Thereupon he exclaimed: “It is clear that I slept for seventy years!” He then caught sight of his donkey who had given birth to several generations of mules, and he returned home. He there enquired: “Is the son of Honi the Circle-Drawer still alive?” The people answered him: “His son is no more, but his grandson is still living.” Thereupon he said to them: “I am Honi the Circle-Drawer”, but no one would believe him.

He then went to the Beit Midrash and overheard the scholars say: “The law is as clear to us as in the days of Honi the Circle-Drawer”, for whenever he used to come to the Beit Midrash he would settle for the scholars any difficulty that they had. Whereupon he called out: “I am he!” but the scholars would not believe him nor did they give him the honour due to him. This hurt him greatly and he prayed [for death] and he died…

“Honi HaMeagel”, by Huvy. Honi is famous for drawing a circle in the ground around him and not moving away until God would make it rain. Josephus wrote that Honi was killed during the Hasmonean civil war, around 63 BCE. The Maharsha (Rabbi Shmuel Eidels, 1555-1631) said that people thought he was killed in the war, but actually fell into a deep sleep as the Talmud records.

Honi HaMa’agel, “the Circle-Drawer”, who was renowned for his ability to have his prayers answered, entered a state of deep sleep for seventy years and thereby journeyed to the future! This type of time travel is, of course, not true time travel, and he was unable to go back to his own generation. He prayed for death and was promptly answered.

Travelling back in time, meanwhile, presents far more interesting challenges.

Back to the Future

In 2000, scientists at Princeton University found evidence that it may be possible to exceed the speed of light. As The Guardian reported at the time, “if a particle could exceed the speed of light, the time warp would become negative, and the particle could then travel backwards in time.” This is one of several ways proposed to scientifically explain the possibility of journeying back in time.

The problem with this type of travel is as follows: what happens when a person from the future changes events in the past? The result may be what is often referred to as a “time paradox” or “time loop”. The classic example is a person who goes back to a time before they were born and kills their parent. If they do so, they would never be born, so how could they go back in time to do it?

Remarkably, just as I took a break from writing this, I saw that my son had brought a book from the library upstairs. Out of over 500 books to choose from, he happened to bring Harry Potter and the Prisoner of Azkaban. Now, he is far too young to have read it, or to even known who Harry Potter is. And yet, this is the one book in the Harry Potter series—and possibly the one book in our library—that presents a classic time paradox!

In Prisoner of Azkaban, we read how Harry is about to be killed by a Dementor when he is suddenly saved by a mysterious figure who is, unbeknownst to him, his own future self. After recovering from the attack, he later gets his hands on a “time turner” and goes back in time. It is then that he sees his past self about to be killed by a Dementor, and saves his past self. The big problem, of course, is that Harry could have never gone back in time to save himself had he not already gone back in time to save himself in the first place!

Perhaps a more famous example is James Cameron’s 1984 The Terminator. In this story, John Connor is a future saviour of humanity who is a thorn in the side of the evil, world-ruling robots. Those evil robots decide to send one of their own back to a time before John Connor was born in order to kill his mother—so that John could never be born. Aware of this, Connor sends one of his own soldiers back in time to protect his mother. The soldier and the mother fall in love, and the soldier impregnates her, giving birth to John Connor! In other words, future John Connor sent his own father back in time to protect his mother and conceive himself! This is a time paradox.

Could we find such a time paradox in the Torah? At first glance, there doesn’t appear to be anything like this. However, a deeper look reveals that there may be such a case after all.

When God Wanted to “Kill” Moses

In one of the most perplexing passages in the Torah, we read that when Moses took his family to head back to Egypt and save his people, “God encountered him and sought to kill him.” (Exodus 4:24) To save Moses, his wife Tziporah quickly circumcises their son, sparing her husband’s life. The standard explanation for this is that Moses’ son Eliezer was born the same day that he met God for the first time at the Burning Bush. Moses spent seven days communicating with God, then descended on the eighth day and gathered his things to go fulfil his mission.

However, the eighth day is when he needed to circumcise his son, as God had already commanded his forefather Abraham generations earlier. Moses intended to have the brit milah when they would stop at a hotel along the way, but got caught up with other things. An angel appeared, threatening Moses for failing to do this important mitzvah, so Tziporah took the initiative and circumcised her son. Alternatively, some say it was the baby whose life was at risk.

Whatever the case, essentially all the commentaries agree that God had sent an angel to remind Moses of the circumcision. Who was that angel? It may have been a persecuting angel, and some say he took the form of a frightening snake. Others, like the Malbim (Rabbi Meir Leibush Weisser, 1809-1879) say it was an “angel of mercy” as Moses was entirely righteous and meritorious. Under the circumstances, one’s natural inclination might point to it being the angel in charge of circumcision, as suggested by Sforno (Rabbi Ovadiah ben Yakov, 1475-1550). Who is the angel in charge of circumcision? Eliyahu! In fact, Sforno proposes that the custom of having a special kise kavod, chair of honour, or “chair of Eliyahu” (though Sforno doesn’t say “Eliyahu” by name), might originate in this very Torah passage. Every brit milah today has such an Eliyahu chair, for it is an established Jewish tradition that the prophet-turned-angel Eliyahu visits every brit.

‘Elijah Taken Up to Heaven’

Yet, Eliyahu could not have been there at the brit of Moses’ son, for Eliyahu would not be born for many years! Eliyahu lived sometime in the 9th century BCE. He was a prophet during the reign of the evil king Ahab and his even-more-evil wife Izevel (Jezebel). The Tanakh tells us that Eliyahu never died, but was taken up to Heaven in a fiery chariot (II Kings 2). As is well-known, he transformed into an angel.

The Zohar (I, 93a) explains that when Eliyahu spoke negatively of his own people and told God that the Jews azvu britekha, “have forsaken Your covenant” (I Kings 19:10), God replied:

I vow that whenever My children make this sign in their flesh, you will be present, and the mouth which testified that the Jewish people have abandoned My covenant will testify that they are keeping it.

He henceforth became known as malakh habrit, “angel of the covenant”, a term first used by the later prophet Malachi (3:1).

If Eliyahu is Malakh haBrit, and is present at every circumcision, does this only apply to future circumcisions after his earthly life, or all circumcisions, even those before his time? As an angel that is no longer bound by physical limitations, could he not travel back in time and be present at brits of the past, too? God certainly does transcend time and space, and exists in past, present, and future all at once. This is in God’s very name, a fusion of haya, hoveh, and ihyeh, “was, is, will be”, all in one (see the Arizal’s Etz Chaim, at the beginning of Sha’ar Rishon, anaf 1). And we already saw how God could send Moses to the distant future and bring him right back to the past. Could He have sent Eliyahu back to the brit of Moses’ son? Such a scenario would result in a classic time loop. How could Eliyahu, a future Torah prophet, save Moses, the very first Torah prophet? Eliyahu could not exist without Moses!

It is important to note here that there were those Sages who believed that Eliyahu was always an angel, from Creation, and came down into bodily form for a short period of time during the reign of Ahab. This is why the Tanakh does not describe Eliyahu’s origins. It does not state who his parents were, or even which tribe he hailed from. Others famously state that “Pinchas is Eliyahu”, ie. that Eliyahu was actually Pinchas, the grandson of Aaron. Pinchas was blessed with eternal life, and after leaving the priesthood, reappeared many years later as Eliyahu to save the Jewish people at a difficult time. He was taken up to Heaven alive as God promised. In the Torah, we read how God blessed Pinchas with briti shalom (Numbers 25:12). Again, that key word “brit” appears—a clue that Pinchas would become Eliyahu, malakh habrit.

While it is hard to fathom, or accept, the possibility of an Eliyahu time paradox, there is one last time paradox that deserves mention. And on this time paradox, all of our Sages do agree.

The Paradox of Teshuva

When we read our Sages description of the process of teshuva, “repentance”, it is hard not to notice the inherent time paradox lying within. In multiple places, our Sages state that when a person truly repents, the sins of their past are expunged from their record. They are not only erased, but it is as if they never happened to begin with. Some go further and state that not only are the sins completely erased, they transform into merits! (Yoma 86b) In other words, it is almost as if one’s soul travelled back in time and, when presented with that same challenge, actually fulfilled a mitzvah instead! It is much like the classic literary version of a hero going back in time to fix an old mistake. This is the tremendous power of teshuva. It may be the closest any of us will ever come to time travel.

That same page of Talmud goes further in saying that one who truly repents lengthens one’s life. To explain, when a person sins it may be decreed in Heaven that their life will be cut short. When they repent, the sin is erased and so is the decree, so their life is re-extended. Imagine such a parallel in the physical world: a person is a smoker or heavy drinker for decades, then quits and “repents”, and all the damage done to the cells and organs of their body simply vanish. They are instantly as good as new! It doesn’t happen in the physical world, but it does in the spiritual world. Repentance for the past actually has a real impact on one’s future, rewriting one’s destiny, much like time travel.

Finally, that same page of the Talmud states that one who truly repents hastens the Redemption. The Sages reaffirm countless times that the arrival of the Redemption is based solely on our merits. If Israel only “hearkens to His voice”, the Redemption would come “today” (Sanhedrin 98a). The fact that so much time has passed and Mashiach has still not come is a result of our own sins. By wholeheartedly repenting, we wipe away those sins of the past. Like time travel, this rewrites our destiny—our history—and we thereby hasten the Redemption.

Chanukah & the Light of Creation

Tonight we light the second candle of Chanukah. As is well-known, Jewish law forbids using the light of the Chanukah candles for mundane purposes. At first thought, this is strange since all other holiday candles which we light may be used for mundane purposes. One can have a candle-lit dinner with the Shabbat candles on the table, yet the same cannot be done with Chanukah candles. This is actually why we light an additional (“ninth”) candle called the shamash, whose job is to “protect” the light of the Chanukah candles so that we do not inadvertently make use of them. Why is it that the Chanukah lights must not be used? To answer this question one must go all the way back, long before the Maccabees, to the very beginnings of the universe.

The Light of Creation

When we open the Torah we read how God’s first act of Creation within an empty universe was light. God said “Let there be light”, and so it was. A few paragraphs later, we read that on the fourth day God created various luminaries to “give light”, including the sun, moon, and stars. If the things that naturally give off light were only created on the fourth day, what was the light of the first day? The Sages (Chagigah 12a) grappled with this apparent contradiction:

But was the light created on the first day? …This is [to be explained] according to Rabbi Elazar, for Rabbi Elazar said: “The light which the Holy One, blessed be He, created on the first day, one could see thereby from one end of the universe to the other; but as soon as the Holy One, blessed be He, beheld the generation of the Flood and the generation of the Dispersion, and saw that their actions were corrupt, He arose and hid it from them…”

Now the Tannaim [differ on the point]: “The light which the Holy One, blessed be He, created on the first day one could see and look thereby from one end of the universe to the other,” this is the view of Rabbi Yaakov. But the Sages say: It is identical with the luminaries; for they were created on the first day, but they were not “hung up” until the fourth day.

On the simple level, the Sages agreed that the light of the first and fourth days were really the same thing: while God created the luminaries on the first day, He only set them in their specific locations and orbits on the fourth day. This is in line with another opinion that God really created everything in one instant, on the first day, and on the subsequent “days” He simply put everything in its place. [For an explanation of this, see the Ramak’s (Rabbi Moshe Cordovero, 1522-1570) Pardes Rimonim 13:5.]

On a deeper level, as expounded by Rabbi Elazar and Rabbi Yaakov, the light of the first day was an entirely different entity. Unlike the familiar, physical light of the fourth day, the light of the first day was a special, mystical light which contained the power for one to see across the universe, through all of time and space. According to the Zohar, this is the special radiance of Creation, from which all things were fashioned (as we’ve written in the past). This idea is already noted in the Midrash (Beresheet Rabbah 12:6) which adds that “the light with which God created the universe [was given] to Adam, and with it he stood and gazed from one end of the universe to the other.”

Adam and Eve were given this Divine Light as a gift. However, once they consumed the Forbidden Fruit, that light disappeared. In fact, the Kabbalists explain that initially Adam and Eve saw the world entirely through this Divine Light, and themselves glowed with this light, and when they looked upon each other, they saw only each other’s light, which is why they were unashamed. After consuming the Fruit, that light disappeared, and when they looked upon each other they saw frail skin, and all of its lustful trappings. This is why they were suddenly ashamed and wanted to hide.

The Kabbalists explain that this is the mystical meaning of the interplay between the words for “light”, or (אור), and “skin”, ‘or (עור), words that sound the same and are written which just one substitution: The singular, holy aleph replaced with the ‘ayin, which literally means “eye” and represents this illusory physical world. Before the Fruit, Adam and Eve saw light; afterwards they saw only skin. (See Beresheet Rabbah 20:12, Zohar I, 22b, and Pardes Rimonim 13:3)

This is the deeper meaning behind God’s first word to Adam and Eve after their fall: “Ayeka?” The term literally means “Where are you?” referring to the fact that Adam and Eve were hiding because they were ashamed. Of course, God knew exactly where they were. So what did He mean by Ayeka?

Ayeka

The Sages explain that the original Divine Light, called Or HaGanuz, the “hidden light”, only shone for 36 hours. There are two opinions as to how one reaches this number. The first (as in Beresheet Rabbah cited above) is that the Light shone for the entire 24 hours of the first Shabbat, as well as the 12 hours preceding that Shabbat, from the moment that Adam and Eve were created on the sixth day. The light disappeared at Shabbat’s conclusion, which is one reason why we perform Havdallah at the end of Shabbat, symbolizing our hope for the restoration of that Light. Alternatively, the Light shone for the first three days of Creation, before those physical luminaries were created on the fourth day. Since each day had 12 hours of light and 12 hours of dark, that means each of the three days had 12 hours of this Divine Light, totalling up to 36.

In reality, both opinions are correct. The Divine Light initially shone for those first three days—36 hours—and was then concealed by the new physical luminaries. On the sixth day, when God created Adam and Eve, He entrusted them with that Light, and they possessed it for 36 hours until the conclusion of the first Sabbath, neatly mirroring those 36 hours of the first three days. When Adam and Eve consumed the Fruit, the Light disappeared from them, and was taken back up to Heaven, stored beneath God’s Throne (Yalkut Shimoni, Isaiah 499). This brings us back to Ayeka. The gematria of that word (איכה) happens to be 36. When God called out to Adam and Eve and said Ayeka, what He meant was not “where are you?” but “where is the Light?”

‘Garden of Eden’, by Thomas Cole

Restoring the Light

While the Or HaGanuz has been hidden for now, it reveals itself in this world through several channels. We find that same number 36 in a number of important places. Most notably, when we look at the actual number of texts in our Holy Scriptures, we find that there are 36: Genesis, Exodus, Leviticus, Numbers, Deuteronomy, Joshua, Judges, Samuel, Kings, Isaiah, Jeremiah, Ezekiel, Hoshea, Yoel, Amos, Ovadiah, Yonah, Micah, Nahum, Habakkuk, Tzephaniah, Haggai, Zechariah, Malachi, Psalms, Proverbs, Job, Song of Songs, Ruth, Lamentations, Ecclesiastes, Esther, Daniel, Ezra, Nehemiah, and Chronicles. While we generally group these texts into 24 “books” of the Tanakh for convenience, there are exactly 36 independent works. This reminds us that the Holy Scriptures contain within them the Divine Light, and through the study of these texts we can receive a glimpse of it.

Similarly, the Bnei Issachar (Rabbi Tzvi Elimelech Shapiro, c. 1783-1841) points out that there are 36 tractates to the Talmud. Study of Torah—whether Written (Tanakh) or Oral (Talmud)—serves to restore that Divine Light little by little. Naturally, this parallels the idea of the 36 Perfect Tzaddikim. The Sages state that in every generation there are exactly 36 perfectly righteous people alive, and the world only continues to exist in their merit (Sanhedrin 97b). They contain a spark of that Divine Light within them. And on the calendar, too, there is a month in which finding the Or HaGanuz is particularly auspicious. This is the month of Kislev which, the Bnei Issachar points out, is a contraction of kis (כס) and lev (לו), the former meaning “hidden” and the latter having the value of 36.

That brings us right back to Chanukah, which begins on the 25th of Kislev. We light one candle on the first day, two on the second, and so on. The total number of candles lit over the course of eight days just happens to be 36. The Chanukah lights are symbolic of that special holy light of Creation. One should not for a moment think that these are just mundane, physical lights. And this is the mystical reason for why Jewish law forbids using the Chanukah lights for any purpose. One should constantly meditate on the fact that the light of the Menorah represents the Or HaGanuz, the light of Creation, the holy light with which Adam and Eve “saw from one end of the universe to the other.”

Jewish law also requires one to place their Menorah in a widely visible spot. We must “publicise the miracle” as much as possible, hence the many public Menorah-lighting ceremonies that take place around the world, and the many electronic chanukiahs found outside synagogues, in shopping malls, and on the roofs of cars. We are not just commemorating the Chanukah miracle, but the Jewish mission to bring light into the world (as Isaiah 42:6 famously states).

From a mystical perspective, we light 36 candles to remind ourselves that our mission is to rectify the cosmos and reveal the primordial holy light of God. We remind ourselves that we should strive to return to being like the original Adam and Eve, who glowed with this light, and who looked past the deceptive skin to see the pure light within each other. When we learn to recognize each other’s inner glow, then we will merit a return to the luminous Garden of Eden.

Chag Sameach!

Red Cow: Quantum Physics in the Torah

This week’s parasha, Chukat, begins with the laws of the Red Cow (or “Red Heifer”). The Torah describes in detail the Red Cow ritual, starting with the production of a special mixture which alone had the power to remove the greatest of impurities, the impurity of death. (Because we lack this mixture today, everyone is considered ritually impure at all times, and this is one reason why most Orthodox authorities discourage Jews from ascending the Temple Mount in Jerusalem.) First, the Torah requires finding a perfectly red calf. The Sages elaborate that even two non-red hairs invalidate a cow. The calf must also be entirely unblemished, and in perfect health. It must not have ever been used for any kind of labour. The simple act of putting a yoke on the cow—even if just for a moment—immediately disqualifies it.

Rabbis inspect a red cow in Israel (Courtesy: Temple Institute). Jewish tradition maintains there have only been nine red cows used in history. The tenth will come in the time of Mashiach.

Once such a cow is found, it is taken to the Temple and appropriately slaughtered. The High Priest takes some of its blood and sprinkles it towards the Holy of Holies (or the “Tent of Meeting”). The cow is then entirely consumed in flames, with the added ingredients of cedar wood, hyssop, and crimson wool. At this point, the High Priest has become impure himself, and must go to the mikveh. Another priest (who is pure) must gather the ashes to be used to make the purifying solution. This person, too, becomes impure. Finally, the third pure person who actually prepares the mixture and sprinkles it on the impure people also becomes impure in the process. Perplexingly, the act of purifying others instantly makes the purifier himself impure.

This strange Red Cow ritual puzzled the ancient Sages. They went so far as to say that even King Solomon—the wisest of all men—could not understand the Red Cow (Yoma 14a). The Sages base themselves on Solomon’s own words (Ecclesiastes 7:23): “All this have I tried by wisdom… but it was far from me.” Solomon had all the wisdom, yet there was one thing that was too “far” for him to grasp, and that was the Red Cow. (The Midrash, meanwhile, comments on Solomon’s words in Proverbs 30:18—“Three things are wondrous to me, and four I do not know”—to mean that Solomon didn’t know seven more things.  The three things wondrous to him were the secrets of the Pesach offering, matzah, and maror; and the four he didn’t know were the mysteries of the four species of Sukkot. See Vayikra Rabbah 30:14)

The Sages conclude that the Red Cow has no human logic and is, as the Torah states, a chok, an incomprehensible divine law. In other words, no one understands the Red Cow.

The Nazis tried to ban Einstein’s theories and discoveries. They didn’t like quantum physics very much, and once branded it as a “Jewish science”.

Interestingly, there is a parallel phenomenon in the world of science. The past century and a half has seen the rise of a bewildering new field called quantum physics. Like the Red Cow ritual, many experiments in quantum physics yield results that are incomprehensible. They often contradict the foundational principles of classical physics, and are sometimes just plain bizarre. This may be why Albert Einstein once humorously described quantum physics as a “talmudical theory”. (And may be why Jews are so disproportionately represented in the field.) Niels Bohr, meanwhile, said something along the lines of “Those who are not profoundly shocked when they first come across quantum theory have not understood it.” And Richard Feynman concluded: “I think I can safely say that no one understands quantum mechanics.”

Quantum physics is to science what the Red Cow is to the Torah. In fact, a closer examination may reveal a very intimate connection between the two.

Entanglement

One of the central principles of quantum physics is entanglement. This refers to two particles that are intertwined, and appear to affect one another instantaneously even though they may be very far apart. For example, take the case of two entanglement particles, one with a clockwise spin, and the other with a counter-clockwise spin. If the clockwise particle is forced to spin the other way, the counter-clockwise particle immediately changes its spin as well. This is true even over vast distances, and the effect is immediate, suggesting faster-than-light communication. Einstein famously called this strange phenomenon “spooky action at a distance”.

Entanglement has the potential for many practical applications, and scientists are even working on an un-hackable “quantum internet”. Meanwhile, Stuart Hameroff and Roger Penrose have built an entire biological theory around entanglement, which provides a scientific explanation for the soul, the afterlife, and reincarnation.

Of course, from a Jewish mystical perspective, all souls are intertwined and “entangled”. Entanglement may even explain the strange nature of the Red Cow. Recall that when the pure person sprinkles the mixture upon the impure person, he instantly becomes impure himself while the impure person becomes pure. This is precisely like a counter-clockwise particle instantly switching its spin to clockwise when its fellow entangled particle is made to go from clockwise to counter-clockwise.

Uncertainty Principle

Another foundation of quantum physics is Heisenberg’s Uncertainty Principle. In short, this means that when measuring any given particle, we can either determine its position, or its speed, but not both. If we measure its position, then technically at that split instant the particle isn’t really in motion, so we cannot determine its speed. If we measure its speed, than it can’t be standing still in any one position, so we cannot determine exactly where it is. (The principle can be explained with a classic physics joke: a police officer pulls over a speeding particle and asks: “Do you have any idea how fast you were going?” The particle replies: “No sir, but I know where I am.”)

Rav Yitzchak Ginsburgh beautifully points out that the Torah actually speaks of the Uncertainty Principle. We read in Job 28 of the difference between man’s limited wisdom and God’s omniscience. We are then told that “God understands her path, and He knows her place.” (Job 28:23) Unlike man, who is incapable of grasping such things, God alone knows both the “path” (momentum) and “place” (location) of a particle! Rav Ginsburgh summarizes:

Now, what is the verse saying? Actually, it is saying exactly what Einstein said when he heard that the uncertainty principle was somehow inherent in nature: “God does not play dice with the universe.” It did not sit well with him that God cannot see beyond the uncertainty principle. Little did Einstein know that he had a verse in the Bible to support his intuition that God does know… (Lectures on Torah and Modern Physics, pg. 90)

Wave-Particle Duality

Perhaps the most well-known principle in quantum physics is that of wave-particle duality. This is the notion that every particle is also a wave. The discovery was a result of a much earlier debate (going back at least to the time of Newton) of whether light is a particle or wave. Over the decades, experiments would alternately show that light behaves as a particle, while others would show that light behaves as a wave. Eventually, it was found that photons (particles of light) behave in both ways, and the same is true for other particles, too.

Closely related to this is what is known as the “observer effect”, that the presence of a conscious “observer” actually affects whether a particle will behave as a particle or wave. In the famous double-slit experiment, whenever scientists “watch” a particle it always passes through one slit and leaves a single mark on the screen behind as expected. Yet, whenever they remove the measuring devices and shoot particles without any observation, the particle seemingly goes through both slits simultaneously, and produces a wave-like pattern on the screen!

Notions like this led Max Planck, often called the “father of quantum physics”, to conclude:

As a man who has devoted his whole life to the most clear-headed science, to the study of matter, I can tell you as a result of my research about atoms this much: There is no matter as such. All matter originates and exists only by virtue of a force which brings the particle of an atom to vibration and holds this most minute solar system of the atom together. We must assume behind this force the existence of a conscious and intelligent mind. This mind is the matrix of all matter.

Rav Ginsburgh once more shows how wave-particle duality is secretly embedded in the language of the Torah. The Torah’s word for a “wave” is gal (גל), while the Torah’s word for a tiny drop, or “particle”, is egel (אגל). The two share one root, meaning there is a profound connection between them. Rav Ginsburgh cites ancient commentaries (ibid, pg. 128-129) which explain how a multitude of tiny drops of dew blanketing a field combine to form the appearance of a wave. The Sages are speaking of an observer who seems to be looking at a wave but, upon closer examination, is seeing individual particles of dew. This is little more than a poetic way of describing the scientific “observer effect”, where close observation and measurement shows particles while lack of measurement shows waves.

String Theory in Kabbalah

For decades, physicists have been looking for a “theory of everything” that can elegantly explain all of the various phenomena in the universe. Currently, one very popular such theory is string theory, which holds that the universe boils down to a set of tiny vibrating strings. Differing vibrations would result in particles of different masses and charges, giving rise to the variety of forces and particles in the universe, including a particle that carries gravity (called a graviton). String theory is therefore a good “theory of everything” that can neatly unify all of physics.

Edward Witten is also Jewish, and the son of Louis Witten, another well-known physicist.

In reality, string theory is not one theory, and has multiple versions. In the past, there were five major, accepted models. Then, in 1995 Edward Witten was able to unify these models into one wholesome theory, called M-theory, sparking a “superstring revolution”. Since then, a great deal of work has been done to strengthen and support M-theory, which continues to be one of the leading models in modern physics.

Interestingly, M-theory suggests that the universe has a total of 11 dimensions. Three of these are the familiar dimensions of space (length, width, height). The fourth is the dimension of time, which is really inseparable from the three of space, and part of one continuum. In addition to these, there are seven more dimensions unperceivable to human senses:

 

Etz Chaim, “Tree of Life”, showing the upper sefirot (Keter/Da’at, Chokhmah, and Binah, known as the Mochin), and the seven lower sefirot.

Anyone who has dabbled in Kabbalah will immediately recognize that this conception of 11 dimensions perfectly parallels the “dimensions” of Kabbalah, ie. the Sefirot. In the arrangement of the sefirot, too, we have the three sefirot of the mochin, which are tied to a fourth (usually hidden) sefirah of Da’at, just like the three spatial dimensions are intertwined with time. Below the three mochin are the seven middot. Like the 11 dimensions of M-theory, the Kabbalistic “Tree of Life”—as made popular by the Arizal—is typically shown depicting 11 sefirot. (Yet, the Sages insist that there are ten sefirot, never eleven! It should be noted that in non-M-theory versions of string theory, there are indeed only 10 dimensions.) One who studies both M-theory and the Arizal’s teachings of the sefirot will quickly find tremendous overlap between them.

And one who has delved into the Kabbalah of the Arizal will know just how easy it is to get lost in descriptions of dimensions within dimensions, and universes superimposed upon universes; in souls entangled across vast distances, and across eons of time; and in lengthy formulas of yichudim, kavvanot, and tikkunim (“unifications”, “meditations”, and “rectifications”). In fact, studying the Arizal sometimes feels like studying quantum physics. Truly, the two go hand-in-hand, and are poised to bridge the gap between the realm of science and the realm of the spirit.

The Mystical Purpose of the Omer

“Bringing the Omer to the Kohen” by Ahuva Klein

In this week’s parasha, Emor, we read of the commandment to count the Omer. Each of the forty-nine days between the holidays of Pesach and Shavuot must be enumerated. In Temple times, this went along with a special “wave-offering” consisting of sheaves (omer in Hebrew) of barley. The Torah doesn’t clearly spell out why this must be done. However, a big clue is given from the conspicuous interplay between the words Emor (the name of the parasha) and Omer (the mitzvah commanded in this parasha).

The difference between Emor (אמר) and Omer (עמר) is just a single letter: an aleph replaced with an ayin. Our Sages point out that when two words differ in such a way, there is a special connection between them. The letter aleph is the first in the alphabet, with a value of one, representing the One God. (In fact, an aleph is composed of two yuds joined by a vav, the sum of which is 26, equal to God’s Ineffable Name, Yud-Hei-Vav-Hei). Each Hebrew letter is also a word with its own meaning. “Aleph” means “master” or “chief”, once more hinting to God being the Master of the Universe. Ayin, meanwhile, means “eye”. The eyes are the tools with which we see this physical world. Because of this, the eyes mislead us, distracting us from the truth that everything is truly One. Indeed, the Shema that we recite twice daily cautions not to follow “after your eyes”. The aleph therefore represents spirituality, while the ayin represents physicality.

The Ramak (Rabbi Moshe Cordovero, 1522-1570) suggests that Israel represents the unique, spiritual nation among the seventy root nations of the world that are trapped in physicality, the value of ayin being 70. Here (Pardes Rimonim 13:3), he gives the most famous example of the interplay between aleph and ayin: The Sages state that Adam and Eve were initially created as beings of light (אור). Only after consuming the Forbidden Fruit did their light disappear, replaced with fragile skin (עור). Other examples of such parallel terms described in mystical texts include “me” (אני) and “poor” (עני), “nothingness” (אין) and “eye” (עין), and the words in question: “emor” (אמר) and “omer” (עמר).

“Emor” means to speak. It is one of three major roots for “speaking” in Hebrew. The Zohar (I, 234b) explains that ledaber (לדבר) refers to simple, day-to-day speech; le’emor (לאמר) is to speak from the heart; and lehagid (להגיד) is to speak from the soul. For more practical examples, a simple, everyday Torah insight is called a dvar (דבר), while a long and in-depth discourse is a ma’amar (מאמר), and on Pesach we have a particularly special text that comes straight from the soul called the haggadah (הגדה). The form of speech we are interested in here is emor—speech of the heart.

What is the connection between this type of speech and the Omer?

32 Paths of Wisdom

Sefer Yetzirah, perhaps the oldest Jewish mystical text, explains how God brought about the universe. It begins by stating that God created through 32 Paths of Wisdom. These 32 paths are the 22 letters of the Hebrew alphabet and the 10 Sefirot (as explained here). Sefer Yetzirah tells us that the first letters God forged were aleph, mem, and shin, which brought about the three primordial elements: air (avir or ruach), water (mayim), and fire (esh). These central letters therefore stand at the three horizontal axes of the Kabbalistic “Tree of Life”. The Arizal elaborates (Sha’ar Ruach HaKodesh, drush 2) that God then brought about the substances of the first day of Creation: light, water, and space, ie. or (אור), mayim (מים), and rakia (רקיע). As we read in the Torah, these were the only things in existence at the end of Day One.

The three horizontal lines of the Tree of Life correspond to the paths of the letters Aleph, Mem, and Shin.

You may have already noticed that the initials of these three things make aleph-mem-reish (אמר), “emor”. Amazingly, it is exclusively this verb of speech that the Torah uses in describing God’s creation: v’yomer, God spoke (ויאמר), and everything came to be. It is this form of speech that contains within it the very power of Creation.

Even more amazingly, the Zohar we saw above states that this is speech from the heart. The heart is a special organ for, unlike any other organ, it literally intertwines with every single living cell in the human body, ensuring that the tiniest bodily component receives oxygen and nutrients. So, too, does God permeate the entire universe, and is intertwined with even the tiniest bit of matter, ensuring its continual existence. In Hebrew, “heart” is lev (לב), which has a value of 32, once more alluding to those 32 paths of Creation.

Better yet, the 32 paths correspond to the 32 times that God (Elohim) is mentioned in the account of Creation. It is only after the account of Creation ends, at the 33rd instance, that the Torah introduces us to God’s Ineffable Name. So, too, during the Sefirat haOmer period, we have 32 days before we reach the climax of the whole Omer period, the 33rd day, the holiday of Lag b’Omer. Of course, man is a microcosm of the universe, so it is only fitting that the human body has a spinal cord, with an additional 31 pairs of nerves emerging out of it, sitting beneath the all-important 33rd component, the brain.

With this in mind, we can understand the connection between Emor and Omer.

Rectifying Speech

The Sefirat haOmer period is meant to be one of rectification and purification. Upon the Exodus, the Israelites spent these 49 days preparing to receive the Torah at Sinai. We relive this experience each year, and likewise work on ourselves in these seven weeks. When we count the Omer each night, we quote from the verse in this week’s parasha: “And you shall count for yourselves from the morrow after the day of rest, from the day that you brought the sheaf of the waving [omer hatenufah]; seven weeks shall there be complete; until the morrow after the seventh week shall you count fifty days…” (Leviticus 23:15-16) and then we add, in many versions of the prayer, “in order to purify the souls of Your people Israel from their impurity.” The very purpose of the Omer is personal development and purification. How do we purify ourselves?

The greatest sin that needs to be atoned for is improper speech. The Talmud (Yoma 44a) states that it was for this sin in particular that the Kohen Gadol entered the Holy of Holies just once a year, on Yom Kippur. Conversely, as we saw above, proper speech has the power to create worlds. Impure speech can be immensely destructive while pure speech can rectify anything. King Solomon similarly wrote that “death and life are in the hand of the tongue” (Proverbs 18:21). It is through the mouth that we speak, and the tongue is its primary organ. Beautifully, the mouth, too, contains 32 teeth to parallel the 32 paths of Creation, with the central 33rd component being the tongue.

More than anything else, the purpose of the Omer (עמר) is to allow us to rectify our speech (אמר). The Torah itself hints to this in the verse above, calling the special offering of these 49 days the omer hatenufah, where the latter word can be split (תנו פה) to mean “give mouth”, or “teach the mouth”. Each of the seven weeks that the Torah prescribes correspond to one of the seven mystical middot of the Tree of Life. In the Omer period, we are meant to rectify these seven “lower” Sefirot (hinted in the term Sefirat HaOmer). We do not mention the three “higher” sefirot above. We can understand why this is so, for the Sages say the upper sefirot are the mochin of the mind, while the lower seven are the middot of the heart—and as we saw above, it is the speech of the heart that we are particularly focusing on. The final Sefirah is called Malkhut, “Kingdom”, which Patach Eliyahu (Tikkunei Zohar 17a) says is פה, the mouth. The very culmination of the Sefirat HaOmer period is the purification of speech.

The mochin above (in blue) and the middot below (in red).

Rabbi Akiva’s Students

The Sefirat HaOmer period overlaps with the tragic deaths of Rabbi Akiva’s 24,000 students. As is well-known, the students died because they lacked respect for one another. How exactly did they disrespect each other? Although we have discussed in the past that they were probably killed by the Romans during the Bar Kochva Revolt, the Talmud (Yevamot 62b) cryptically states that they died of a disease called croup. Elsewhere, the Talmud (Sotah 35a) suggests that croup is the standard Heavenly punishment for a person who commits slander. We may learn from this that Rabbi Akiva’s students spoke negatively about each other, and thus deserved their cruel death penalty.

Rabbi Akiva’s students ceased to die on the 33rd of the Omer, as if God was hinting at their misuse of the tremendous powers of speech. One of Rabbi Akiva’s surviving students, Rabbi Shimon bar Yochai, himself had to hide from the Romans for 13 years because he spoke negatively about the authorities. It was he who ultimately fixed the 33rd of the Omer as a holiday. Although this was the day of his death, it was also the day he revealed the depths of Kabbalah, and the teachings that would eventually be compiled into the Zohar. Lag b’Omer is a celebration of this mystical wisdom, much of which is focused on the powers of divine speech.

To bring it all together, we find that the term “lag” (לג) actually appears in the Torah. It is found only in one passage, Leviticus 14, where it refers to a measure of oil, log hashamen. This was a special oil used in the purification procedure for a metzora, loosely translated as a “leper”. The Sages teach that a person would be afflicted with this illness if they spoke negatively about another, motzi shem ra, hence the term “metzora”. Like the Omer, the log hashamen was also a “wave-offering”, a tenufah. Afterwards, the oil was sprinkled and poured upon the leper in order to purify them. If “log” (לג) hints to the oil used to purify improper speech, and Omer (עומר) is the inverse of emor, itself alluding to impure speech, then Lag b’Omer (לג בעומר) takes on an entirely new meaning.

Chag sameach!

How to Receive God’s Blessing

This week’s parasha is Re’eh, which begins by stating:

Behold, I set before you today a blessing and a curse. The blessing, if you will heed the commandments of Hashem your God, which I command you today; and the curse, if you will not heed the commandments of Hashem your God…

God promises that a person who fulfils His mitzvot will be blessed, and one who does not will be cursed. The phrasing is interesting: we might assume it would be clearer to say a person who fulfills God’s mitzvot would be blessed, and one who sins or transgresses the mitzvot will be cursed. Instead, the Torah connects the observance of mitzvot with receiving blessing. What, exactly, is a blessing? And what does it have to do with a mitzvah?

Heaven Down to Earth

The Hebrew word for blessing, brakhah (ברכה), shares a root with two similar words. The first is brekhah (spelled the same way), which means a “pool” or source of water. The second is berekh (ברך), which means a “knee”. What do these seemingly unrelated things have to do with blessing?

Our Sages teach that a blessing is a source of abundance, like a well from which water can be drawn continuously, hence its relation to brekhah. Each blessing in Judaism begins with the words Barukh Atah Adonai, meaning not that we are blessing God (which is impossible), but that we recognize God is the infinite source of all blessing and abundance. The name of God used here is the Tetragrammaton, denoting God’s eternity and infinity, alluded to by the fact that the Name is essentially a conjunction of the verb “to be” in past (היה), present (הווה), and future (יהיה) tenses.

The blessing continues with the words Eloheinu Melekh haOlam. Now, the name of God switches to Elohim, referring to His powers as manifest in this world. Thus, he is described as Melekh haOlam, the “king of the universe”. That same ungraspable, ineffable God permeates every inch of the universe He created, controlling and sustaining the tiniest of details. And so, when we recite a blessing, we are stating that God is the ultimate source of all things, transforming the infinite into the finite, and showering us with constant abundance.

This is where the second related root of berakhah comes in—the knee. Rabbi Aryeh Kaplan explains that the purpose of the knee is to allow a person to bend down or descend. Thus, when one recites a blessing, they are causing God to “descend” into this world, so to speak, and bless us. When we are blessing, what we are really doing is receiving a blessing. This is alluded to by the very root letters of the word for blessing, beit (ב), reish (ר), and khaf (כ), whose corresponding numerical values are 2, 200, and 20, respectively. These doublets represents the two-way nature of a blessing.

Plugging in to the Source

Our holy texts affirm that God is constantly showering us with blessings. Yet, oftentimes it may seem like our lives are devoid of blessing. What’s going on? Imagine walking out into a torrential rain and trying to catch the water with your bare hands. No matter how much water is pouring over you, it is unlikely that you will succeed. Now imagine doing the same thing with a bucket in each hand.

The same is true for blessings. One needs the appropriate vessel to receive the abundance. In this case, the vessel is the person. To receive holy blessings, the vessel must be made holy. This is accomplished through the performance of mitzvot, which are designed to rectify and sanctify the person.

On a deeper level, the purpose of the mitzvot is to bind a Jew directly to God. In fact, it is taught that the root of mitzvah actually means “to bind”. God is the Infinite Source of all things, and if one wants to receive from the Infinite, they must only tap into It and form the right connection. Once such a connection is made, there is no end to how much blessing can be obtained.

This is why the parasha begins by telling us that a person who fulfils the mitzvot will be blessed, while a person who does not fulfil them will be “cursed”, devoid of all blessing. It is also why Jews going to receive a berakhah from a great tzaddik are often given a blessing only on the condition that they take upon themselves some kind of mitzvah. The same is true in prayer, during which it is customary to give tzedakah, tying our requests with the fulfilment of an important mitzvah.

Every mitzvah that is done opens up another channel of Heavenly Light, and each time it is repeated that channel is widened and reinforced. In fact, our Sages speak of precisely 620 channels of light shining down into this world, corresponding to the 613 mitzvot of the Torah, and the additional 7 mitzvot instituted by the rabbis (or the additional 7 Noahide laws).

As we enter the month of Elul and begin a forty day period of heightened repentance and prayer, we should be thinking about which mitzvahs we can take on, which we might improve upon, and how we can further sanctify ourselves in order to become the purest possible vessel of divinity. We mustn’t forget that the blessing is always shining down upon us; we must only be prepared to receive it.
