There is a tradition of the Brahmins that Rama had two sons, Kusha and Lahu. They went with their mother to a city, where they dwelt with a great hermit of the time. Lahu, a young lad, went out to wander through the town and look at its beauty. To his great surprise he found a beautiful horse running without a rider. And when he enquired whose horse it was, people said, "This horse is let loose with the intention that anyone who can catch it shall be crowned as king of this country."
