If somebody punches you in the mouth and says, "You are terrible," you should be grateful that such a person has actually acknowledged you and said so. You could, in fact, respond with tremendous dignity by saying, "Thank you, I appreciate your concern." In that way his neurosis is taken over by you, taken into you, much as is done in tonglen practice. This is an immense sacrifice taking place here. If you think this is ridiculously trippy, you are right. In some sense the whole thing is ridiculously trippy. But if somebody doesn't begin to provide some kind of harmony, we will not be able to develop sanity in this world at all. Somebody has to plant the seed so that sanity can happen on this earth.
