Once, while the deities Vishnu and Brahma contested for superiority, Shiva appeared as a flame, and challenged them to find his source. Brahma took the form of a swan, and flew to the sky to see the top of the flame, while Vishnu became the boar Varaha, and sought its base. The scene is called Lingodbhava and is represented in the western wall at the sanctum of most on Shiva temples. Neither Brahma nor Vishnu could find the source, and while Vishnu conceded his defeat, Brahma lied and said he had found the pinnacle. Angry at this, Lord Shiva took the form of Kala Bhairava and took apart one of the five faces of Lord Brahma and in punishment, Shiva ordained that Brahma would never have temples on earth in his worship.
