Once a man went to a Chinese sage and said to him, "I want to learn the occult laws. Will you teach me?" The sage said, "You have come to ask me to teach you something, but we have so many missionaries in China who come to teach us." The man said, "We know about God, but I have come to you to ask you about occult laws." The sage said, "If you know about God you don't need to know anything more. God is all that is to be known. If you know Him you know all."
