There is a story of a young man who became a wrestler at the court of the King of Persia. No one knew anything about his ancestry except the king, who had brought him up with great care. This wrestler, whose name was Kushtam, became the champion of his country, and was trying to become a world champion. But the king would not allow him to meet foreigners or even to talk to them. He wrestled with many wrestlers and every time he won, but the custom of the time was that the one who was defeated had to acknowledge his defeat or be killed.
