Neither Brahma nor Vishnu could find the source, and while Vishnu conceded his defeat, Brahma lied and said he had found the pinnacle.

The Lingodbhava image can be found in the first precinct around the sanctum in the wall exactly behind the image of Shiva in the central shrine with Vishnu and Brahma in the sides. Lingodbhava or emergence of the Lingam , found in various "puranas", augments the synthesis of the old cults of pillar and phallic worship. The idea emerged from deity residing in a pillar and later visualised as Shiva emerging from the lingam. Shiva is represented in South Indian temples in the phallic form of Lingam. The image of Lingothbhava is depicted with Shiva emerging from Linga in his original form. Vishnu in the form of boar is usually depicted in the bottom of the phallus while Brahma in the form of a gander is seen on the top of the phallus. In some temples, Lingothbhava is depicted in  this form along with Brahma on the right of the image while Vishnu to the left of Shiva, both worshipping Shiva emerging as a column of fire. Lingobhava along with Dakshinamurthy is considered the most common forms of Shiva in the South Indian temples from Chola times. Literary mention. "Tirukkural", the classic Tamil language couplets has the first mention of Lingothbhava which mentions that Shiva wanted to express his supremacy over Vishnu and Brahma. Appar, one of the early Shaiva saint of the 7th century, gives evidence of this knowledge of "puranic" episodes relating to Lingodbhava form of Shiva while  Tirugnana Sambandar refers this form of Shiva as the nature of light that could not be comprehended by Brahma and Vishnu. Thiruvathirai festival is celebrated during the Tamil month of "Margazhi" (December - January) in all Shiva temples when Shiva is believed to have performed the cosmic dance. The same day as per "Arunachala Puranam", the literary history of Annamalaiyar Temple, is considered the day when Shiva rose as a column of fire when both Vishnu and Brahma could not find his origin. The living beings in the three worlds could not bear the heat of column and at the request  of celestial deities, Shiva cooled down as the mountain Arunachala. The Shivaratri when he cooled down is called the Lingothbhavar day. The day is considered when the genesis of mixture of form and formless manifestation of Shiva.
