The Bris Maamar (בעצם היום הזה)

The classic bris maamar from Torah Ohr. A classic for a reason. If there’s one specific shiur here that I think people are most likely to seek out actively, I would think it’s this one. The Alter Rebbe explains the three levels of refinement that Hashem bestows/will bestow upon us, and he explains why Avraham Avinu waited for so long to undergo circumcision.
