Vishnu is one of the principal deities of Hinduism, and the Supreme Being in its Vaishnavism tradition. Vishnu is the “preserver” in the Hindu trinity (Trimurti) which includes Brahma (Creator) and Shiva (Destroyer of Sorrows and provides Cosmic Balance).
Vishnu is identical to the formless metaphysical concept called Brahman, the Supreme, who takes various avatars as “the preserver, protector” whenever the world is threatened with evil, chaos, and destructive forces. His avatars most notably include Rama in the Ramayana and Krishna in the Mahabharata.
