Jagannatha is a deity worshipped in regional Hindu traditions in India as part of a triad along with his (Krishna's) brother Balabhadra, and sister, Subhadra. Jagannath, within Odia Hinduism, is the supreme god, Purushottama, and the Para Brahman. To most Vaishnava Hindus, particularly the Krishnaites, Jagannath is an abstract representation of Krishna, or Vishnu, sometimes as the avatar of Krishna or Vishnu. To some Shaiva and Shakta Hindus, he is a symmetry-filled tantric form of Bhairava, a fierce manifestation of Shiva associated with annihilation.

Vaishnavism is one of the major Hindu denominations along with Shaivism, Shaktism, and Smartism. It is also called Vishnuism since it considers Vishnu as the sole supreme being leading all other Hindu deities, that is, Mahavishnu. Its followers are called Vaishnavites or Vaishnavas, and it includes sub-sects like Krishnaism and Ramaism, which consider Krishna and Rama as the supreme beings respectively. According to a 2010 estimate by Johnson and Grim, Vaishnavism is the largest Hindu sect, constituting about 641 million or 67.6% of Hindus.
