Thomas Moore began his lecture at the UUMA Convo in Ottawa today with a story about emptiness. Nazruddin went to preach to a group of people, and when he got there he asked, "How many of you have heard me preach before?" The excited group of fans all raised their hands. He said, "Very good. You've heard me before, and so you already know what I would say." And he left. The next day he came back and asked the group, "How many of you have heard me preach before?" They'd learned their lesson, so none raised their hands. Then he said, "Well, if you've never heard me preach before, you won't understand what I was going to say." And he left. The next day he came back and asked, "How many of you have heard me preach before?" This time the confused crowd was split, and half raised their hands and half didn't. Nazruddin said, "Good. Those of you who heard me preach before, explain what I said to those who haven't." And he left.
