The Killing of the Demon Narakaasura
The demon Narakaasura was the evil king of Pragjyotishpur, near Nepal. He ruled with a reign of terror, abducted 16,000 daughters of the gods and stole the earrings of Aditi, mother of the gods. The gods asked Lord Krishna for help and, after a mighty battle, he killed the demon, freed the girls and recovered the earrings.
The rescue of the 16,000 girls is said to be the origin of the story that Krishna had 16,000 wives.
After his victory Krishna returned very early in the morning and was bathed and massaged with scented oils.
