In Indian mythology, the lord of death. The Vedas describe him as the first man who died. The son of the sun god Surya, he presides over the resting place of the dead. In the Vedas, he was a cheerful king of the departed ancestors, but in later mythology he became known as the just judge who punished the deceased for their sins
1 Controller, Ordainer, Lord of the Law; in the Rg-veda he seems to have been originally a form of the Sun, then one of the twin children of the wide-shining Lord of the Truth; he is the guardian of the dharma, the law of the Truth, which is a condition of immortality, and therefore himself the guardian of immortality; in the later ideas [post-Vedic] he is the God of Death
He is represented as of a green color, with red garments, having a crown on his head, his eyes inflamed, and sitting on a buffalo, with a club and noose in his hands
