A story of Rinzai:
One of his disciples was talking with another religious master's disciple
who said, "Our master is a man of miracles. He can do
anything he wants. I have seen many miracles he has done, I have witnessed
them myself. What is the great thing about your
master? What miracles can he do?"
And the disciple of Rinzai said, "The greatest miracle my master can do is
not to do miracles."
