So I had a teacher who said "listen to everyone and believe no one." The Buddha said the same thing, that you shouldn't believe his teachings because he said it. Rather, believe it if your experience verifies his words.
My Buddhist sewing teacher showed me how to remove chalk marks from my sewing. It didn't work very well. I asked her if I could wash it... and she said no... but then explained to me how to wash it (was there a double message here?). In any case I washed it... and got rid of many of the chalk marks... and then removed more with a fancy eraser. But it is rippled a bit... so I thought I'd find another godless religion, or jump off a bridge after watching a movie trailer about people who do that... or maybe just confess in my blog and leave it at that. So now my sewing is clean and a little dimensional. And since I sit facing the wall in the zendo... who will notice?
