 Vishnuism believes in Vishnu as the supreme being.When all other vaishnavas recognise Krishna as one of Vishnu's avatars, though only the krishnaits identify the Supreme Being (Svayam Bhagavan, Brahman, a source of the Tridev) with Lord Krishna and his forms (Radha Krishna, Vithoba and others), those manifested themselves as Vishnu.This is its difference from such groups as Ramaism, Radhaism, Sitaism, etc.
