A Mystical Map of Your Soul

This week, outside of Israel, we read the parasha of Acharei Mot. (In Israel, since Pesach is seven days and finished last Friday, Acharei Mot was read on Shabbat and this week the following parasha, Kedoshim, is read. For the next few months, the weekly parasha read in the Diaspora will be different than that read in Israel.) In Acharei Mot, we are commanded:

And any man of the House of Israel or of the foreigner that lives among them, who eats any blood, I will set My countenance upon the soul who eats the blood, and I will cut him off from among his people. For the soul of the flesh is in the blood, and I have therefore given it to you [to be placed] upon the altar, to atone for your souls. For it is the blood that atones for the soul. (Leviticus 17:10-11)

Many recipes call for the use of “kosher salt”. Chefs like it because the larger grains allow them to season their meals more precisely. Jews use koshering salt to remove the tiniest drops of blood that may have remained after draining.

The Jewish people are absolutely forbidden from consuming any kind of blood, whether in a juicy steak or even the tiniest drop inside an egg. It is quite ironic that one of the most disgusting anti-Semitic accusations thrown upon the Jews is that Jews, God forbid, consume the blood of children. (It is all the more ironic that this “blood libel” originates among Catholics who, when taking communion, believe they are drinking the blood of Jesus—who was a Jew!) In reality, Jews obsess over ensuring that we consume no blood whatsoever, and one of the requirements of kosher meat is that all of the blood has been completely removed.

The Torah explains that we should not consume blood because nefesh habasar b’dam hi, the “soul of the flesh is in the blood”. If we eat meat, it is in order to obtain the nutrients in the flesh, not to absorb the spirit of the animal. The animal’s soul is, as the Torah commands, to be placed “upon the altar”. The Kabbalists explain that by doing so, the soul of the animal is allowed to return to the spiritual worlds from which it originates.

In precisely balanced language, the verses cited above state that a Jew who consumes any blood within which is soul, nefesh, will be “cut off” from his nation, and God will personally set His wrath upon that Jewish soul, nefesh. The same word is used to refer to the soul of the Jew and that of the animal. People sometimes forget that animals, too, have souls, and it is forbidden to harm animals in any way.

Having said that, there is of course a great difference between the soul of an animal and the soul of a human. In fact, we find in the Tanakh that five different words are used to refer to the soul. Our Sages explain that a person actually has five souls, or more accurately, five parts or levels to their soul. (The Ba’al HaTurim, Rabbi Yakov ben Asher [1269-1343], states that the five prayer services of Yom Kippur, and the five times that the Kohen Gadol would immerse in the mikveh that day, is in order to purify all five souls; see his commentary on this week’s parasha, Leviticus 16:14.) These five souls are in ascending order, and correspond to the spiritual universes of Creation and to the divine Sefirot. Each soul is itself made up of even smaller, intertwining parts. Understanding the soul and its dynamics is a central part of Jewish mysticism, and what follows is a brief overview of that spiritual map.

The First Three Souls

The first and lowest of the souls is the nefesh. As we have already seen, this soul is associated with the blood, and is the “life force” of a living organism. Above that is the soul called ruach, literally “wind” or “spirit”. We find this term right at the beginning of the Torah (Genesis 1:2) in referring to the Spirit of God (Ruach Elohim) and in many other places to refer to the souls of great people, such as Joshua (Numbers 27:18). Above that is the neshamah, literally “breath”, which we are first introduced to during the creation of Adam, where God breathes a nishmat chayim, “soul of life” into the first civilized man (Genesis 2:7).

These first three souls—nefesh, ruach, and neshamah; often abbreviated as naran—are spoken of widely across Jewish holy texts, from the Tanakh through the Talmud and the Zohar. For example, the Talmud (Niddah 31a) states how there are three partners in the creation of a person: the father is the primary source of five “white” things (bones, nerves, nails, brain, eyeball), the mother is the primary source of five “red” things (blood, skin, flesh, hair, iris), and God gives ten things, including the ruach and neshamah. (The nefesh presumably goes together with the blood from the mother.)

The Zohar (I, 205b-206a) elaborates that the neshamah is greater than the ruach, which is greater than the nefesh, and that a person only accesses higher levels of their soul if they are worthy. Sinners do not have access to their neshamas at all. They are just living nefesh, like animals. Based on this, the Zohar has a unique perspective on Genesis 7:22-23:

All in whose nostrils was the breath of the spirit of life [nishmat ruach], whatsoever was in the dry land, died. And He blotted out every living substance which was upon the face of the ground, both man, and cattle, and creeping thing, and fowl of the sky; and they were blotted out from the earth; and Noah alone was left, and they that were with him in the ark.

The Zohar sees these two verses as distinct. First, all those people who did merit a ruach and neshamah (meaning they weren’t completely sinful and didn’t deserve to perish in the Flood) died of natural causes. Only after this did God “blot out” all that remained, including animals and people who were so sinful they were essentially like animals, bearing only a nefesh.

With these three souls in mind, many aspects of life can be better understood. For example, when one is asleep only the nefesh remains in the body (to keep it alive), while the higher souls may migrate. This is why a sleeping body is unconscious and likened to a corpse, and why sometimes dreams can be prophetic, as the higher souls may be accessing information from the Heavens, or through interaction with other souls.

Another intriguing example is from Ibn Ezra (Rabbi Abraham ben Meir ibn Ezra, 1089-1167) who relates the three souls to three major purposes of sexual intercourse. The first and simplest is for procreation, something that even animals do, and naturally corresponds to nefesh. The second is for good health, corresponding to ruach. The third is for love and intimacy, fusing the souls of husband and wife, corresponding to the neshamah.

In addition to naran, the Zohar sometimes speaks of additional, even higher souls, such as “nefesh of Atzilut” and “neshamah of Aba and Ima” (see II, 94b). To make sense of these, we must turn to the Arizal.

Earning Your Higher Souls

In multiple places, Rabbi Chaim Vital (1543-1620), the primary disciple of the Arizal (Rabbi Isaac Luria, 1534-1572) and the one who recorded the bulk of his teachings, describes the anatomy of the soul (see, for example, the first passages of Sha’ar HaGilgulim or Derush Igulim v’Yosher 3 in Etz Chaim). At birth, a baby only contains a full nefesh. As the Torah states, the nefesh is in the blood, and the Arizal adds that since the liver filters blood and is full of it, it is the organ most associated with nefesh. By the age of bar or bat mizvah, a person now has the ability to fully access their ruach. The organ of ruach is the heart (also stated in the Zohar, III, 29b, Raya Mehemna), associated with one’s drives, and both inclinations, the yetzer hatov and the yetzer hara. Only at age 20 does the neshamah become fully available (in most cases). The neshamah is housed in the brain, and is associated with the mind.

Today, we know how scientifically precise those statements are. For example, at any given time the liver (the body’s largest internal organ) contains about 10% of the body’s blood volume, and filters about a quarter of all blood each minute. As well, we know today that the majority of the brain’s development ends around age 20 (though minor changes continue for at least another decade, if not longer). It therefore isn’t surprising that teenagers are so good at making bad decisions. We can also understand why being a teenager is so difficult emotionally, as this is when the ruach is in full force in the heart, and one struggles with their desires and inclinations.

Reinforcing what was said in the Zohar, the Arizal taught that one does not automatically have full access to these souls, but must work on themselves and merit to attain them. Unfortunately, a great many people spend their entire lives stuck in nefesh, living very materialistic and animalistic lives, never overcoming their desires and inclinations (ruach), or achieving any kind of mental greatness (neshamah). The potential is there, though never realized.

For those who do grow ever-higher, they may be able to access even loftier soul levels: the chayah and yechidah. In the Torah, we see many places where the soul is referred to as chayah, including right at the start where God breathes a soul into Adam and makes him l’nefesh chayah (Genesis 2:7). The chayah is sometimes described as an aura. It is not housed within the body, but glows outward, and plays an important role in the interactions between people.

Above it is the highest level of soul, the yechidah, “singular one”, which connects a person directly with God. It is like a divine umbilical cord, and one who realizes it and senses it may certainly draw through it information from Above. The yechidah, too, has Scriptural basis, for example in Psalms 22:21 and 35:17 where David asks God to save his nefesh and yechidah from danger.

Souls Intertwined With Universes

In Etz Chaim, Rabbi Vital cites the Talmud (Berakhot 10a) as the source for the concept of five souls, as well as the five olamot, spiritual universes. (The mystical Sefer HaBahir adds that this is the secret of the letter hei, which has a numerical value of five.) There in the Talmud, the Sages point out how David’s Barchi Nafshi, Psalms 103-104, uses the phrase Barchi nafshi et Hashem, “May my soul bless God” five times. These, the Sages state, correspond to the five olamot, “worlds” or “universes” that David inhabited. Though the Talmud goes on to present a more physical explanation of what these worlds are, it is possible to read deeper between the lines, and the Kabbalists find allusions to five cosmic, spiritual universes, which are: Asiyah, Yetzirah, Beriah, Atzilut, and Adam Kadmon. While explaining these worlds in depth is a topic for another time, we can state that the five souls correspond to these five universes.

In fact, the Arizal teaches that one can identify the soul elevation of another by studying the colour of their aura: black is the colour of Asiyah, the lowest, physical realm which we visibly inhabit. The higher world of Yetzirah, the domain of angels and spirits, is red. Even higher is Beriah, literally “Creation”, where the very spiritual foundations of Creation exist. It is white. Above this is Atzilut, “divine emanation”, which is pure, brilliant light. These worlds, and souls, correspond to the letters of God’s Name. The final hei is Asiyah/Nefesh, the vav is Yetzirah/Ruach, the first hei is Beriah/Neshamah, the yud is Atzilut/Chayah, and the “crown” atop the yud is Adam Kadmon/Yechidah.

How the letters of God’s Ineffable Name relate to the five levels of soul, the five “universes”, and the Ten Sefirot. (Zeir Anpin refers to the middle six Sefirot from Chessed to Yesod.)

All of these also correspond to the major branches of Torah study. Learning Tanakh is in Asiyah, while Mishnah is in Yetzirah. Talmud is in Beriah, while Kabbalah is in Atzilut. When one learns these texts, they are putting on a spiritual “garment” for that soul level, rectifying it and elevating it further, and this garment will remain with them in the World to Come (see Sha’ar HaPesukim on Tehilim). This is the deeper meaning of Psalm 19:8, which states that God’s Torah is temimah, meshivat nefesh, is “pure and restores the soul”.

Adam Kadmon is left out of the above (and in general is made distinct from the other four universes) because that level is where one has mastered all of the Torah branches, has refined their soul to the highest degree, and is a perfectly righteous person. This level may be equated to the super-lofty soul of Nefesh d’Atzilut which we previously mentioned from the Zohar. Such a rare person is referred to as a malakh, an “angel”, and this was the case with people like Eliyahu, Yehudah, Hezekiah, and Enoch (Sha’ar HaGilgulim, ch. 39).

How the souls and universes relate to the “Tree of Life” which depicts the 32 Paths of Creation – the 10 Sefirot and the 22 Hebrew letters.

Emptying The Universe’s Soul

In case it wasn’t complicated enough just yet, the Arizal taught that each of the five souls is itself composed of five souls. So, within the nefesh, ruach, neshamah, chayah, and yechidah (abbreviated as naran chai) there is an inner nefesh, ruach, neshamah, chayah, and yechidah! That makes 25 smaller parts to the soul. Furthermore, each of these parts is composed of 613 sparks corresponding to the 613 mitzvot. Each of those sparks is further composed of 600,000 even smaller sparks. Multiplying them all together, we get 9.195 billion sparks.

In the same place where he writes this (Sha’ar HaGilgulim, ch. 11), Rabbi Vital explains that all of these sparks were contained within Adam. We may assume that it probably isn’t the case that each person has 9 billion or more sparks, but that Adam’s original soul divided up into so many sparks. Since it is said that in the same way all people are physical descendants of Adam, they are also his spiritual descendants, we might conclude that the world should expect to have a population of up to 9.195 billion people. Interestingly, demographers are currently predicting that Earth’s population will actually top out around 9 billion, and will then start to decline. This prediction is quite amazing in light of one famous Talmudic teaching:

In Yevamot 62a, the Sages state that Mashiach will not come until all souls are born. They describe a Heavenly repository of souls called guf, literally “body”. Only when guf is empty can Mashiach arrive. The guf may be mystically referring to that first “body” of Adam which contained all souls within it. Once all of those sparks are born, all souls from the beginning of time will be alive simultaneously so that everyone can witness the tremendous Final Redemption. It appears we are inching ever closer to that moment.

The Secret Behind Wearing Masks and Getting Drunk

This Wednesday evening marks the start of the festive holiday of Purim. There are four central mitzvot to be done on Purim: listening to the reading of Megillat Esther, sending gifts of food to one’s fellow, giving charity to two or more people in need, and enjoying a holiday feast. In addition to these, there are two well-known and widespread Purim customs: dressing up in costumes, and getting inebriated. Although these two customs are unfortunately sometimes taken to improper extremes, the meanings behind them are quite profound.

Searching For Yourself

1882 Lithograph of ‘The Disgrace of Vashti’

The practice of wearing costumes comes from the Megillah itself. One of the major themes of the Purim story is the characters “dressing up”. First there’s Vashti, who is asked by her husband to get dressed up in her royal garments and present herself before all of his guests (Esther 1:11-12). She refuses to do this, thereby losing her queenship. A search for a new queen begins, and the winner is a modest Jewish girl who has no interest in being a royal. The humble Hadassah is dressed up and transformed into the Persian Queen Esther. (Ironically, while “Esther” is a very common Jewish name today, Esther’s own Jewish name was Hadassah; “Esther” was her non-Jewish name, from the very non-Jewish idol Astarte, or Ishtar. Of course, Esther does have a Hebrew root as well, meaning “hidden”, which fits neatly into the Purim story.)

There is more dress up to follow: Haman wishes to be dressed up in the king’s robes and, in another bit of irony, it is Mordechai who ends up being costumed as king (Esther 6:6-11). The Talmud (Megillah 12a) adds that King Ahashverosh came to his banquet dressed up in the special garments of the kohen gadol, the Jewish high priest. Some are of the opinion that the reason he held the banquet in the first place was to mark the end of the prophesied 70-year exile of the Jewish people, which he miscalculated. With the Jews remaining in exile as his subjects, he felt a victory banquet was in order. Dressing up as the kohen gadol was meant to symbolize the end of Jewish hopes of returning to their Promised Land and rebuilding their Temple, with Ahashverosh himself now being their “high priest”.

‘The Triumph of Mordechai’ by Pieter Lastman (1624). Historical records from Ancient Persia show that there was indeed a courtier to the Persian king in Shushan (Susa) named Marduka. It looks like he was originally the king’s accountant.

So, wearing costumes is a major Purim theme right from the Megillah. And the Megillah is full of many more hidden identities. The Talmud (Megillah 12b) reveals that Memuchan (Esther 1:16), the advisor who instructs King Ahashverosh to get rid of Vashti, is the same person as Haman. Meanwhile, Hatach (4:5), Esther’s trusted attendant, is one and the same as the prophet Daniel (Megillah 15a). The Talmud also brings an opinion that Mordechai was really the prophet Malachi. (“Mordechai”, too, appears to be his non-Jewish name, based on the name of the supreme Babylonian deity, Marduk.)

Therefore, the custom of getting dressed up and taking on a different identity is very much in the spirit of Purim. In ancient times, Purim was more specifically celebrated with a masquerade. Why wear a mask? Why hide who we really are? The truth is, we don’t just get “dressed up” on Purim. Each of us puts on a metaphysical mask every day of our lives, and we wear different masks in different settings. There is the mask that we wear at work, and the one that we have in front of our kids, and a different mask entirely when we’re out with friends. When can we really be ourselves?

In yet another irony (irony is a major theme of Purim, too), we only get the chance to truly be ourselves when we hide behind a mask! It is behind a mask—when no one can recognize us—that we finally feel free to let go and be ourselves. This is hinted to in the Hebrew word for getting costumed up, l’hitchapes (להתחפש).

In Hebrew, a verb that begins with the prefix l’hit (להת) is reflexive, ie. something that you do to yourself. For example, lirchotz (לרחוץ) is to wash something, while l’hitrachetz (להתרחץ) is to wash one’s self. To dress a child is lehalbish (להלביש), while to get yourself dressed is l’hitlabesh (להתלבש). The verb for putting on a costume, l’hitchapes (להתחפש), is reflexive. What does it mean when we remove the reflexive prefix? Rav Yitzchak Ginsburgh beautifully points out how it becomes l’chapes (לחפש), “to search”. In other words, l’hitchapes—to put on a costume—literally means “to search for yourself”!

It is often only when we mask our identity that we can act as we truly are. This can be a powerful tool for introspection and self-discovery. It can especially reveal one’s vices, and this will hopefully allow a person to recognize what they have to work on to become a better person. On Purim, there is huge potential for real teshuva, “repentance”, like no other time. No wonder that our Sages compared Purim to Yom Kippur, and it is commonly said that Yom HaKippurim (the way it is referred to in the Torah) can be read Yom k’Purim, “a day like Purim”.

Alcohol has a similar function.

What Alcohol Does to Your Brain

The human brain is a complex network of billions of neurons that interact chemically and electrically with each other. The molecules that turn these neurons on and off are called neurotransmitters. The brain’s main excitatory neurotransmitter is glutamate, while its main inhibitory neurotransmitter is gamma-aminobutyric acid, or GABA for short. Alcohol in the brain causes an increase in GABA. (Others hold that alcohol doesn’t necessarily increase the amount of GABA, but binds the same receptors, causing the same inhibitory effect.)

The result is a steady “shutting down” of more and more of the brain. Inhibition in the prefrontal cortex would cause poor decision making. Inhibition in the motor cortex would affect movement, and in the occipital lobe, vision. Speech is slurred, hearing is affected, and the more alcohol that is consumed, the more of the brain is suppressed. If a person drinks far too much alcohol it could be fatal because eventually even the brain stem, which controls vital functions like breathing, will be inhibited.

Now, a person should certainly not drink anywhere near that amount. But, alcohol in moderation does allow a person to mellow out, loosen up, and act more like themselves. In this way, drinking alcohol is similar to putting on a costume. By drinking a little bit, a person can discover who they really are. This is further assisted by the fact that GABA is also involved with reorganizing the brain, and causing the formation of new neurons and new synapses, or connections. (Note: this does not mean that alcohol is somehow healthy or that it should be imbibed regularly. On the whole, it is damaging to the brain and possibly even worse for the liver.)

The Talmud (Sanhedrin 38a) states nichnas yayin, yatza sod, “when wine goes in, secrets come out.” One can understand this statement on two levels: the simple meaning is that, as everyone knows, a person who gets drunk is quite likely to let their mouth run wild and spill their secrets. On a deeper level, “secrets” may refer not to one’s own inner secrets, but to the secrets of the Torah.

One who has a few drinks, inhibits their conscious mind a little bit (maybe even stimulates the formation of some new synapses a little bit) might able to peer deeper into the Torah, revealing previously unknown secrets. One such mini-secret is hidden within that Talmudic statement itself, where the gematria of “wine”, yayin (יין), is 70, equal to the value of “secret”, sod (סוד). Nichnas yayin, yatza sod; seventy goes in and seventy comes out. What the Talmud is saying (and what neuroscience has now confirmed) is that alcohol may lead one to think more creatively, or outside the box, or differently than the way they usually do.

The Kabbalah of Ad d’Lo Yada

When it comes to drinking on Purim, the Talmud (Megillah 7b) famously states that a person should drink to the point of ad d’lo yada, “not knowing” the difference between “Blessed is Mordechai” and “Cursed is Haman”. This statement is highly problematic. One would have to be incredibly intoxicated not to know such a basic distinction, yet Jewish law prohibits a Jew from ever being so heavily under the influence. Most halachic authorities maintain that a person should drink just enough to feel soft and sleepy. So, why describe such an extreme state of intoxication on Purim?

Basic Gematria Chart

In reality, drinking on Purim isn’t at all about getting smashed to the point of losing control. On the contrary, what we should be doing is drinking just enough to allow us to see beyond. Nichnas yayin, yatza sod—take in a little to reveal those hidden secrets. The clue is in that very maxim, where “wine” and “secret” had the same gematria, 70. Now, look at “Blessed is Mordechai” (ברוך מרדכי) and “Cursed is Haman” (ארור המן). The gematria of these two terms is also the same, 502! When the Talmud states that one should drink until they can’t tell the difference, what it really means is that one should drink until they can look more acutely, and recognize that the two are numerically the same. The message is to look deeper into the text to find the secrets hiding within. That is, after all, the main theme of Purim. It is the very meaning of Megillat Esther, which can literally be translated as “revealing the hidden”.

Why would the gematrias of “Blessed is Mordechai” and “Cursed is Haman” be the same to begin with? This brings us back to the first idea that Purim is about discovering our true selves. Mordechai and Haman are equal because they represent two forces which reside inside each person. There is Mordechai, the yetzer hatov, the good inclination; and Haman, the yetzer hara, the evil inclination. The two are in a constant struggle with each other, each seeking to gain the upper hand, and it is our duty to nurture the former and restrain the latter.

On Purim, when we wear costumes and get a little inebriated, one or the other may get the upper hand. For some, hiding behind a mask and mellowing out makes them a better person, while for others it makes them worse. If we take the time and effort to observe ourselves carefully in that state—observe our thoughts, words, and actions—we can thereby understand ourselves more thoroughly, and discover what we need to do to maintain the right balance of “Blessed is Mordechai” and “Cursed is Haman”, 502 and 502. We can learn how to better nurture the good inclination, and more effectively restrain the other one. In fact, this is alluded to in another term from the Megillah which has that numerical value. At the end of the narrative, we read the following important verse:

Now in the twelfth month, which is the month of Adar, on its thirteenth day, when the king’s commandment and his decree drew near to be put in execution, in the day that the enemies of the Jews hoped to rule over them, it was turned to the contrary: that the Jews had rule over those that hated them… (Esther 9:1)

In this verse we find the key term v’nahafoch hu, that everything was “turned upside down”. On Purim, sibru oivey haYehudim lishlot bahem, “the enemies of the Jews hoped to rule over them”, but then everything flipped around and the Jews dominated their enemies instead. The words haYehudim lishlot bahem, literally “the Jews, dominated over them”, has a gematria of 502 as well. Perhaps there is a latent message here for each of us today, all Jews, to dominate over them, our inclinations, our 502s. To learn to become fully in control of ourselves. That way, regardless of whether we are inebriated or sober, in costume or not, we will always be completely righteous and holy.

This Purim, look deeper inside the text, and deeper into yourself. Drink a little and get in costume; be yourself, observe your actions and words very carefully, and aim to discover who you really are.

Chag sameach!

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”.

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.
