Does the Rebbe support learning in Kollel? Who, if anyone, should be learning Torah full-time? And which institutes of Torah learning meet the Rebbe's standards—and which might be better off closed down? In this letter the Rebbe lays out his vision for a productive Kollel, and the class explores the Rebbe's exacting standard when it comes to what sort of Kollel—and what sort of students—the Rebbe wants to see in his institutions.
