A series of classes exploring Bris Mila. We begin with the RaMbaM, the Midrash and the More' Nivuchim. This is followed up with The Tanya (Iggeres HaKodesh 4) and Torah Ohr (Lech Lecha.) Then we have several Sichos, including one about אין למדין מלפני מתן תורה and the fact that the Bris is called the Bris of Avrohom.
