Vishnu (; ) is a Hindu god, the Supreme God of Vaishnavism (one of the three principal denominations of Hinduism) and one of the three supreme deities (Trimurti) of Hinduism. He is also known as Narayana and Hari. As one of the five primary forms of God in the Smarta tradition, he is conceived as "the Preserver or the Protector" within the Trimurti, the Hindu Trinity of the divinity. In Hindu sacred texts, Vishnu is usually described as having dark complexion of water-filled clouds and as having four arms. He is depicted as a blue being, holding a padma (lotus flower) in the lower left hand, the Kaumodaki gada (mace) in the lower right hand, the Panchajanya shankha (conch) in the upper left hand and the discus weapon Sudarshana Chakra in the upper right hand.
