When my zeide described how Reb Aizel would become excited about the Alter Rebbe, it was awesome: “He was the loftiest of men — higher even than Adam HaRishon before the sin. ”
Reb Aizel would say, “If Moshe Rabbeinu came by with the Rebbe, and the Rebbe said, Do this, and Moshe Rabbeinu said, Do that; I would say, ‘ You can do whatever you wish; but there is no way I’ll do anything other than what my Rebbe says. ’”
(Regarding this story the Rebbe wrote to me: As in the story of Rabbeinu Tam and Moshe Rabbeinu, in Seder HaDoros, Section 1, 49304.)
