Likkutei Sichot: Volume VI - Bereishis

The Sin of The tree of Knowledge: Why couldn't Adam show restraint, and how does the whole story relate to us? The importance of facing up to the challenge of our own evil inclination, the vital role of a woman and the immense effect it has on a Jewish Home.

The Flood, The Tower of Bable and their relevance to us living in a post-Holocaust era. Also, the differences between the two generations, and the lessons they impart.

Why Abraham delayed the Mitzvah of circumcision until he was commanded by G-d, and the virtue of our Torah observance today over that of the Patriarchs.

The Mitzvah of Honoring guests: Why the Rambam attributes the establishment of this Mitzvah to Abraham. Also, the connection of Abraham's tamarisk tree to promoting Jewish Education.

"Just as their days are perfect so too their years perfect" Why the Torah chooses to accredit perfection of the righteous to chronological age and an elderly appearance; the necessity of both excelling in personal spiritual growth and positively affecting the world at large during our lifetime.

"Yitzchak the son of Avraham; Avraham begat Yitzchak”, Two interconnecting explanations, one mystical and one practical as to why the Torah uses this seemingly redundant sentence.
