Stages of Spiritual Development

Last week, we discussed the distinction between body and soul, and the need to develop each in its own way. The pure soul must be freed of the kelipot that encapsulate and suppress it, while the animalistic body must be refined and strengthened, both externally and internally. We are reminded of this again in this week’s parasha, Ekev, where Moses famously poses “What does Hashem, your God, ask of you?” The answer is to fear God, walk in His ways, to love Him, and to serve Him with all of one’s heart and soul, as well as to fulfill His mitzvot. We are then told to metaphorically “circumcise our hearts” (Deuteronomy 10:16). This, too, is an allusion to the kelipot, those spiritual “foreskins” that must be removed.

What we didn’t discuss last week is how exactly this process of refinement is accomplished. Aside from the general directive to fulfill mitzvot, what specifically needs to be done at each level of spiritual development? How does a person know whether they are in the “nefesh” stage, or the “ruach” stage? Should one focus on “neshamah”, or are they ready for “chayah”? This is what we will examine this week.

The Science of Chametz

As we continue celebrating Pesach this week, and avoiding all things chametz, it is important to take a moment and explore what exactly is chametz? While we spend a tremendous amount of time and effort learning about, and implementing, the various halakhot regarding eliminating chametz, we rarely think about what chametz actually is on the chemical level. If we did know, it would help to clarify what specifically is forbidden, and might save us a great deal of time and effort in our preparations. It would also help us better understand what actually happened in Egypt with our ancestors millennia ago (the answer may surprise you). So, what is chametz? Continue reading

Secrets of God’s Ineffable Name

In this week’s parasha, Shemot, God first reveals Himself to Moses. He introduces Himself thus: “I am the God of your forefathers; the God of Abraham, the God of Isaac, and the God of Jacob.” (Exodus 3:6) Later on in the conversation, Moses asks God how he should tell the Children of Israel about God, and what name should he use in referring to God? God replies that He is Ehyeh Asher Ehyeh, “I will be what I will be”. The simple meaning here is that God is trying to convey that He is not some idol or pagan deity. He has no shape or form; he has no location. He is everywhere and imbues everything. He is everything. He will be whatever He needs to be; wherever, whenever. Only after that introduction, God says:

Thus shall you say to the children of Israel: YHWH, the God of your fathers; the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you; this is My name for ever, and this is My memorial unto all generations. (Exodus 3:15)

God reveals His eternal name: YHWH (יהוה), a term so holy and powerful it is not uttered. It is referred to as God’s “Ineffable” Name, or just the Tetragrammaton (literally the “four-letter” name), and by Jews as Hashem (“The Name”), or Adonai (“My Lord”) in prayers or Torah readings. Some Jews refer to it by rearranging the letters and saying Havaya. (Some non-Jews have transliterated it into English as “Jehovah”.) Whatever the appellation, this name of God carries infinite depths of meaning. Several of these will be explored below. Continue reading
