There is a story in Tibet about a thief who was a great fool. He stole a large sack of barley one day and was very pleased with himself. He hung it up over his bed, suspended it from the ceiling, because he thought it would be safest there from the rats and other animals. But one rat was very cunning and found a way to get to it. Meanwhile the thief was thinking, "Now, I'll sell this barley to somebody, perhaps my next-door neighbor, and get some silver coins for it. Then I could buy something else and then sell that at a profit. If I go on like this I'll soon be very rich, then I can get married and have a proper home. After that I could have a son. Yes, I shall have a son! Now what name shall I give him?" At that moment the moon had just risen and he saw the moonlight shining in through the window onto his bed. So he thought, "Ah, I shall call him Dawa" (which is the Tibetan name for the moon). And at that moment the rat had finished eating right through the rope from which the bag was hanging, and the bag dropped on the thief and killed him.
