In order to be accepted to his Yeshiva, every new student had to accept the following rules and conditions:
He must learn with all his soul and all his strength and not ever go to bed or to sleep, rather to study until he collapsed from fatigue. He once passed by a student who lay in the hallway, apparently collapsed from tiredness, his head on his folded jacket instead of a pillow. When he awoke, Rebbe Reb Shmelke berated and chastised him: if he still had the strength to fold his jacket and lay down on it, he still had strength left to learn – and that was unacceptable!
