Vishnu, in Hinduism, second deity in the Trimurti (divine trinity, including Brahma, the creator, and Shiva, the destroyer), representing the preserving and protecting aspect of the godhead. The ancient Vishnu Purana text describes him as the primal god, as do his followers (Vaishnavas), who also worship his many avatars, such as Rama, Buddha, and Krishna. Vishnu is often represented dark blue in color, holding in his 4 hands a lotus, mace, discus, and conch. His consort is Lakshmi.
