Vishnu, the preservative aspect of the universe and one of the Hindu Trinity, is said to take birth in this mortal world of ours whenever it is overburdened with evil-doers and sinners, who by their wicked actions upset the equilibrium of the earth. One such incarnation is his birth as the son of king Vasudeva and his wife Devaki Devi of bygone ages. He was then given the name of Sri Krishna, and his story is recorded in the famous work of the Hindus known as Bhagavatam.
