The Fasting Rebbe
Torah learning
A story ofRav Nosson Tzvi Finkelהרב נתן צבי בן משה פינקל
Someone once noticed that the Alter fasted often. He found out that the Alter fasted whenever he saw a student who was not succeeding in his learning or his growth.
When asked about it, the Alter replied that if a person truly understood that every talmid is a ben melech, a prince, there was no other choice.
