Version One. (the page numbers and layout are a bit different than the text i used, so you must adopt a little). The idea of חידוש was discussed at length in this class. The point the Rebbe is making is that the idea of חידוש is by a בעל תשובה. The Rebbe links this to שמחת תורה and the postponement of the joy of the Torah from Kippur until Shmini Atzeres and Simchas Torah.

Class Two.This class explains why Shmini Atzeres is called the eighth day and not the first.It’s the eighth day of Teshuva and it’s implications.
