Q: I’m doing research for a writing project. I once heard that R’ Nachman of Breslov promised something regarding boys under a certain age who say tikkun klali at his kever. Is this true? If yes, what was the promise?
A: Shalom!
Rebbe Nachman zal said that if one brought his son to him before the child was seven years old, the child would come to the chupah with a “reineh hemdel” (clean shirt), i.e., a euphemism for (innocence and) purity. After Rebbe Nachman zal passed away, it became customary to bring one’s son to say the Tikkun HaKlali at the kever.
