A young monk was sent to meditate alone in a cave. He mediated for ten years, and developed all kinds of mystical powers, he could fly through the air, he could become invisible, he could dip under the earth, and so-forth. After ten years he returned to his master, and said “Master, see what I have learned.” And then he proceeded to show the master all of his exotic powers. The master frowned and said: “You’ve missed the point. Go back to the cave and start again.”
