A man should never allow himself to be carried away by passion. A man going on a long journey for the purpose of trade left his wife with child. He remained away many years. When he came back he found his wife embracing and hugging a young man. Full of fury he wanted to kill them but restrained himself. Afterwards he made himself known and found to his great joy that the young man was his son whom the wife had borne after his departure.
