Yama
  In Brahmanism, Yama is the god of death and time and the son of the sun-god Vivasvan. He is the king of the realm of the dead and judge of the death. When judging the deeds of man, he is assisted by Chitragupta, a kind of bookkeeper. Yama's wife is Dhumorna, the personification of the fire which burns the dead. His realm is guarded by two four-eyed dogs.

In the Vedic tradition, Yama is the first human who died and found the path to the realm of the dead. He is a son of the sun-god Surya and together with his twin sister Yami they are the progenitors of the human race. The fifth day of the Indian feast of Lamps is dedicated to this pair. In the old-Iranian Avesta, he is the mythical king Yima.

Yami
  In the Vedic tradition, Yami is the mother of mankind. She is the daughter of the sun-god Surya and together with her twin brother Yama they form the first human pair. In Hinduism she is the mother goddess and daughter of Vivasvan. In Tibet, she is the goddess of death who rules of the female spirits of Naraka.
In Buddhism, Yama is the god of death and judge of the death. He belongs to the Dharmapalas (a group of protective deities), but after he was defeated by Yamantaka he rules over Naraka, the netherworld. Ever since his defeat Yama and Yamantaka are eternal enemies. In Tibet, where he is called Schindsche, he is portrayed with the head of a bull or standing on a bull, while having sexual intercourse (Yab-Yum) with a woman. In China he is called Yan-lo and in Japan he is known as Emma-o (or Emma-ten).
