The parable in question, about the child not eating the "black stone" in his pudding, is one that many people report hearing. It might have been in one of the discourses.

I must stress that the individuals and teacher in person were wonderful people and I've absolutely nothing against them. The main issue, without slighting the dead, is Goenka's part. Including the condescending parable.

I would probably go again if I can't find a non-goenka course. But I'd listen to all the discourses and get my annoyance out ahead of time and consider the chanting to be an added difficulty.
