The Difference Between Tish’a B’av and Yom Kippur

R. Avraham Heschel of Apt was opposed to voluntary fasts and self-affliction.

He used to say:
--If I could, I would abolish all the fasts except for the yom ha’mar, the bitter day, Tish’a b’Av and the Yom ha’Kadosh, the Holy Day, Yom Kippur.

On the bitter day -- who can eat?

On the Holy Day – who needs to eat?
