Willi, Reb Shlomo Carlebach Z”L once demurred to serving on a Beis Din, saying, “In my entire life, I never told anybody what to do. I don’t want to start now.” There is also a story in the book Holy Brother about a woman who said she would try shul, provided nobody ever told her what to do. She said I will keep going as long as nobody ever tells me how to act, or to be observant, etc. Each week she went, and sure enough nobody ever told her what to do. Finally after about 6 years, she became frum, and raised a wonderful frum family.
If there was ever an expert in Kiruv, it was Shlomo. Who comes close to his numbers?
