Avataars of Lord Vishnu
Once Lord Brahma becoming tired of his creative activities, wanted to rest. The night of the Brahma was approaching. Because of his tiredness Lord Brahma yawned. All the four Vedas came out from his opened mouth. A demon who used to live near him in disguise, abducted the Vedas. Lord Vishnu took his sixteenth incarnation as Hayagreeva to protect the Vedas. In this incarnation his face resembled that of a horse and the rest of his body resembled that of Sri Narayan with all of his four hands. He killed the demon and protected the Vedas.
