He is highly worshipped in South India., the term `Haya` means `horse` and `Griva` means `neck` in Sanskrit. This deity is depicted with a horse face and a man`s body. Hayagriva`s incarnation took place to restore the Vedas to Lord Brahma
. According to `Devi Bhagarata`, a demon named Hayagriva received a boon that he would never be killed by man or an animal. He started troubling the gods. Devas went to Devi in order to get relief from the demon. They were advised to approach Lord Vishnu. They requested him to be born with the face of a horse and the body of a man to kill Hayagriva.
