Varadharaja Perumal Temple

two sons of sage bringi were the disciples of sage gautama.   they did not notice that two lizards had fallen into the water they brought for their mentor's puja.  gautama cursed them to be changed as lizards.  when they sought a relief, the rishi said it lies in kancheepuram.  after a long journey around the world, they reached kancheepuram and begged lord perumal for salvation.  perumal said that their soul would reach him while their mortal coil would remain in lizard forms.  those who worship the lizards would be relieved of all adverse aspects on them, added perumal.  he also said that sun and moon would be witnesses to this boon.
