In this ma'amar, the Rebbe says over and relays to the shiur the power of preparation in the realm of mitzvos. On the third day Avraham Avinu lifted his eyes and reached his destination, yet Chazal teach us that we are nourished in this world by the two days of preparation and travel that Avraham endured prior to his arrival at the makom akeida. What does it really mean to do hachana for a mitzvah? A life-changing parsha shiur not to be missed!
