Class Two. Questions and answers. Though Korbonos [that the Torah advocates] are higher than Adam, however Neshamos Yisroel are mushrash in Atzmus (HaKadosh Boruch Hu) higher than all. This becomes relevant on Rosh Hashana when all goes back to Atzmus.

Class One. Chapters 2-3 explain how the Neshama is in the Tzelem and Dimus of G-dliness allowing her to experience one of several levels of Achdus. Sin however, cuts this inspiration source off. Then the Neshama needs Korbonos to draw energy from Tohu to compensate for the wrong.
