Krishnaism (also Bhagavatism) is a group of Hindu denominations within Vaishnavism, centered on devotion to Krishna or other forms of Krishna. It is often also called Bhagavatism, because it is the Bhagavata Purana that asserts that Krishna is "Bhagavan Himself," and subordinates to itself all other forms: Vishnu, Narayana, Purusha, Ishvara, Hari, Vasudeva, Janardana, etc.
