Vishnu

Vishnu is one of the principal deities of Hinduism.

The "preserver" in the Hindu triad (Trimurti), Vishnu is revered as the supreme being in Vaishnavism, as identical to the metaphysical concept of Brahman (Atman, the self, or unchanging ultimate reality).

Vishnu is notable in Hindu mythology for adopting various incarnations (avatars such as Rama and Krishna) to preserve and protect dharmic principles whenever the world is threatened with evil, chaos, and destructive forces.
