My zeide told a story in the name of Reb Aizel:
The Mitteler Rebbe once called him over and said, “Aizik, why aren’t you involved with the chassidim?”
“I haven’t a single peaceful moment for myself, ” he answered. “Should I ponder over others’ lives?”
“Aizik … Aizik, ” the Mitteler Rebbe sighed. “Why don’t you learn from me? When I see that I’m a lost case, the least I can do is help out someone else. ”
(This exchange seems to have taken place during the Alter Rebbe’s lifetime.)
