Dattātreya

“[Note: Brahma originally had five heads. He and Vishnu were once contesting each other’s superiority. Just then a huge column of light appeared in front of them and they wondered what it was. They agreed that he who found either end of the column earlier would be the greater of the two. Vishnu became a boar and sought the bottom; Brahma became a swan and flew up towards the top. Vishnu returned disappointed. Brahma at the point of despair came across a falling screwpine flower. He stopped its descent and asked from where it was coming. All that it knew was that it was falling from space and nothing more. Brahma persuaded it to bear false witness and claimed superiority over his rival. Siva was enraged, snipped off that head which spoke the lie, and declared himself as the column of light.]”
