As per Hindu legend, Parvathi, the consort of Shiva, was playing with a ball. As per another variant, she was playing a ball game with Lakshmi and Saraswati. Shiva collated the four vedas as a ball for his consort. To avoid interference, Parvathi disallowed sunset. This resulted in natural calamity leading to the fury of Shiva and kicked away the ball to obscurity. Shiva cursed Parvathi to become a cow and ordered her to worship him in the place where the ball was floated under Kondrai tree. Parvathi in the form of Kamadhenu, the holy cow worshipped the lord in snake's lair in Pandanallur. Vishnu who herded the cow, found the cow devoid of milk one day and canned it. The cow was rescued by Shiva from the lair and Parvathi was freed off the curse. Some variants mention that sage Kanva was having the cow. It was milking an ant hill. When the sage followed the cow, it kicked the anthill under which an image of Linga was found. Following the legend, the image of the Lingam has a mark of hoof. The Lingam is white in colour and ablution is not performed for the presiding deity. The holy cow Kamadhenu milking on an anthill is a common legend associated with most Shiva temples named Pasupatheeswarar, namely the Eswarar worshipped by Pasu, the cow.
