The Rebbe on Chof Kislev, 5737, 1976 said that in the Rebbe Rashab’s Ayin Beis Ma’amarim there are “Gedolos and Niflaos,” greatness and miracles even in comparison to other discourses of the Rashab including Samach Vav. The meaning being that Ayin Beis is far superior in its articulation of Chasidus ideas than any other Ma’amarim of the Rashab.
