This temple overlooks the Aarudhra Kabaaleeswara Temple and is equally magnificient and might have been built around the same time.The temple has several unique features to it. The main deity of the temple is Kasthuri Ranganathar, but he is very different from any other Ranganatha Perumal one might have witnessed in other temples.The legend of the temple says that Durvasa Maharishi, well known for his short temper, once got angry with Lord Brahma and cursed him. Brahma came here and worshipped Lord Vishnu, and got Saapa Vimochana. So true to the legend, the Lord has one arm outstretched and palm extended over Durvasa Maharishi as if to pacify him and the other is stretched towards Brahma who unlike in other Ranganatha temples is not placed on a lotus over the Lord's navel , but he is being held by the Lord over his left hand. One can get to see Durvasa Maharishi by peeping into the Sanctum Sanctorium. The entrance has been deliberately built that way so that the devotees do not disturb the sage and anger him!!!
Another unique feature is that the Dwara Paalakas ( guards ) of the Lord who are usually found on either side of the sannadhi, are found at the feet of the Lord worshipping him!!! These are said to be Devas who had been cursed to become demons and had attained Saapa Vimochana by worshipping Kasthuri Ranganatha and hence are found at his feet serving him!
EVR Periyar 's family has made several contributions to this temple. His father has made the crown and feet of the Lord in Silver ( they are really huge) and his mother has laid the pavement for the devotees to circumambulate.
The Goddess here is called Kamalavalli Thaayar. She looks so serene and welcoming !! A wonderful temple worth visiting if you are in the vicinity!!
