The Rebbe deeply yearns that every bochur think Chassidus, and derives tremendous pleasure from their doing so:
After Yud Shevat Hagadol, Tof Shin Lamed (1970), Reb Shlomo Chaim Kesselman, the famed Mashpia of the Yeshivah in Kfar Chabad, received a Yechidus (private audience) with the Rebbe.
The Rebbe said to him: “How good it would be if it would be possible to demand from every bochur to think Chassidus for ten, twenty, or thirty minutes!” The Rebbe said this in a tone of yearning and intense desire.
The Rebbe expressed interest in one of the Temimim (students in the Chabad Yeshivah). Reb Shlomo Chaim reported that that bochur learns assiduously and thinks Chassidus. The Rebbe responded joyfully, with excitement, “Really, really? He thinks Chassidus as well?” Later on this bochur received a letter of blessing at the Rebbe’s initiative.
