What are the five levels of the neshama for a Jew and the two levels for a non-Jew according to the Zohar? What are their meanings? What are their sources in the Zohar?
The Tanya quotes "zohar 1, 206a" as saying that the 5 levels of the Jewish soul are "nefesh, ruach, neshama, chaya, yechida". [technically the zohar is only referenced as a source for the first 3 levels, but the other 2 are enumerated in a Footnote elsewhere in the tanya and I assume they can be found In the same place in the zohar].
Furthermore, a non Jewish soul consists of only the animal soul (which Jews have as well, in addition to the above soul which can be at one of the above 5 levels).
