Chayey Sara Patriarchs (11) Likutei Sichos vol. 01 page 31-4. Sara (the Zohar says) is the body and Avrohom is the Soul, yet, Avrohom 1) listens to her 2) mourns for her, as she is the purpose.

Vayera Patriarchs (10) Likutei Sichos vol. 35 page 76-81. After all is said and done and Avrohom shows infinite loyalty to Hashem, he begins protesting. In this Sicha the Rebbe shows (in Rashi’s view at least), that Avrohom was never questioning God, but the fact that maybe Hashem thought he was somehow unworthy of giving…

Vayera Patriarchs (09) Likutei Sichos vol. 20 page 73 ff. The Akaida is the last great act of Avrohom’s incredible life. Only at this point is the Mesiras Nefesh of Avrohom Avinu revealed to be totally sacrificial, giving credibility to all the sacrifices he’d made until this point.

Vayera Patriarchs (08) Vol. 10 page 49 ff. Avrohom’s life is divided into two: before and after the Bris. Before he was doing Judaism (like a brick), afterwards he was Jew, a representative of God on this earth (like a stone which is natural and not like a brick which is artificial).

Lech Lecha Patriarchs (06) Vol. 01 page 18 ff. Yishmael’s Bris was rational, and that is a liability compared with Yitzchok’s super-rational bond. It is the basis of the Jewish people and that they are a miraculous people attached to Hashem higher than reason, from infancy.

Lech Lecha Patriarchs (05) Vol. 30 page 53 ff. Bris Mila is two things: 1) a Mitzva, 2) A covenant. In as much as it is a Mitzva, what we do today is separate from what the Avos did, but in as much as it is a Covenant, we continue to bring our children into…

Lech Lecha Patriarchs (04) Vol. 03 page 757 ff. Bris Mila is another step in Avrohom’s spiritual climb. It was the first (and only) Mitzva that he did that actually elevated the physical.

Lech Lecha Patriarchs (03) Vol. 25 page 47 ff. Whatever happened to Avrohom until Lech Lecha (at the age of seventy five) is not written in the Torah, because as the first Jew, his life doesn’t begin until he gets divine instruction and follows with bittul. The lesson for us: we must acquiesce.

Patriarchs (00) (5776/2015) The pact with non-Jews, the Jewish nation, Iyov tells God there will never be another Avrohom Avinu.

Likutei Sichos vol. 8 page 361-2. Notes on Halacha. In this class many original ideas are raised regarding Halacha 4. We also read the deleted part about the false Messiahs and how they carve out the road to Moshiach.
