Synonymous with Krishna, Vishnu is the preserver in the Hindu triad (Trimurti) and is revered as the supreme being In Vaishnavism. Also stated to be synonymous with the sacrifice (e.g. in the Shatapatha Brahmana, see below), Vishnu is particularly notable for adopting various incarnations (avatars such as Varaha, Rama, and Krishna) to preserve and protect dharmic principles whenever the world is threatened with evil, chaos, and destructive forces.
