Vishnu is one of the principal deities in Hinduism, known as the "Preserver" within the Trimurti, a concept in Hinduism that includes the three main deities: Brahma the creator, Vishnu the preserver, and Shiva the destroyer. Vishnu is revered as the supreme being in Vaishnavism, a major tradition within Hinduism. The name Vishnu can be translated to Hebrew as וישנו (Vishnu), although it is not a commonly used term in Hebrew. In Sanskrit, the language in which most Hindu scriptures are written, the name Vishnu means "the all-pervading" or "the pervader." In Tamil, a Dravidian language spoken in South India, Vishnu is referred to as விஷ்ணு (Vishnu). Vishnu is often depicted with blue skin, holding a conch shell, a discus, a mace, and a lotus flower. He is also commonly shown reclining on the serpent Shesha, floating on the cosmic ocean. Vishnu is believed to have incarnated on Earth in various forms, known as avatars, to restore cosmic order and protect the universe. Some of the most well-known avatars of Vishnu include Rama, Krishna, and Buddha. The worship of Vishnu is centered around the belief in his divine interventions and his role in maintaining the balance of the universe.
