Rav Hershel Schachter discussing various halachic topics and minhagim related to Yom Kippur.

The lecture covers a wide range of subjects, including the minhag of immersing in a mikvah before Yom Kippur.

He also explores the obligations and different practices regarding eating on Erev Yom Kippur, questioning whether it is primarily a preparation for the fast or a separate mitzvah.

The discussion moves into the significance of Shabbos when it coincides with Yom Kippur, the background of the custom of Kapparos and its connection to the Zohar, and the origins of the shofar blowing at the end of the day.

Additionally, Rav Schachter provides guidance on the recitation of Viduy, explains details of the Kahon Gadol’s Avodah in the Beis HaMikdash including the requirement to remain in the Azarah, and addresses the prohibition of borer as it applies to Yom Kippur.
