दीपप्रकाशक्षेत्रम्

The moolvar is Deepaprakasar also known as Vilakkoli perumaal in the standing posture.

Thayar is Maragathavalli, and Theertham Saraswathi Theertham and the Vimanam Sreekara Vimanam.

The legend is that the demons in an attempt to disturb the yagna conducted by Brahma darkened the world. Responding to Brahma's prayers Lord Vishnu is said to have manifested Himslef as bright light to enable the yagna to be continued unimpeded. Hence the deity is called Deepaprakasar.

This is the avatara sthala of Swamin Vedantha Desikar and there is a shrine of Desikar with Lakshmi Hayagrivar.

Vaikunta Ekadasi is celebrated in this kshetram.
