021 – Cheshvan 21 - Igeres HaKodesh, Chapter 29 – כ"א חשון – אגרת הקודש פרק כ"ט

From Tanya - regular year - Rabbi Chaim Wolosow by R Chaim Wolosow.

This shiur explains the Alter Rebbe's letter on the Supernal Will, called Kesser Elyon, which stands above wisdom and is clothed in the 613 mitzvos and the 7 Rabbinic mitzvos. Like pillars joining a house's floor to its ceiling, the mitzvos join the highest levels to this world and become garments for the soul.
