Once upon a time a farmer, Gopi, lived in a village. He had few acres of land. One hot afternoon, the poor farmer was digging his field. All of a sudden, his spade hit something. Then he continued his digging. “It is a big metal pot," said Gopi. It was big enough to boil rice for more than hundred people. “It does not seem to be of any use to me. I will dig deeper. May be I will find something else," thought Gopi. He continued to dig.
