There is a story that I have heard with multiple names being used as the Rabbi in the story. It goes like this:
A woman came to [insert name of Torah Sage here] and said that it would enhance her religious experience to wear a Tallis, and could she do so. He advised her to take things step by step, and first try a Tallis without the strings in it and see how she felt. She came back after a week and informed him of how inspired and uplifted she had felt through the experience, and she was ready for the next step. (There are longer versions, but I'll cut to the chase.) [Insert name of Torah Sage here] told her that a four cornered garment without the strings is at best meaningless, so apparently she gets her religious inspiration from something other than Mitzvos, and a Tallis isn't necessary.
Can anyone identify, with credible, documented sources, who the Rabbi in the story was?
