Matsya Purana (Chapter 53) the Hayagriva avatara of Visnu preceded Matsya; when the worlds
were burnt down, Visnu in the form of a horse re-compiled the four Vedas, Vedangas, etc.
The Devi Bhagavata and the Skanda Purana in its Dharnmranya Khanda, however, allude to two
different accounts on the origin of the Hayagriva form of Visnu.
The Kalika Purana records that Visnu in the form of Hayagriva killed the
Fever-Demon (Jvarasura) in the Manikuta hill and lived there for the benefit of men, gods
and asuras. Afflicted with fever and killing the Fever-Demon, Visnu took an agada or
recovery bath. It is called Apunarbhava because whosoever bathes here suffers no second
The Kalika Purana says: -
Na purarjayate yasamattatra Matva narottainah
Apunarbhava samjnam tat sarastu parikirttitam
