Lord Ranganathaswamy is a self-manifested form of Lord Vishnu who lives in Sri Vaikuntam as per the staunch faith of Sri Vaishnavites. Lord Brahma was worshipping Him for a long time and appointed the sun god, Surya, to continue in his absence. Since then the Sun clan has been worshipping the Lord. Lord Sri Ram who belonged to the Sun clan worshipped the deity and after the war with Ravan, to rescue his wife Sita, in recognition for his loyalty and services Lord Ram presented the idol of the Lord Ranganathar to Vibishana. On his way back to Sri Lanka he placed the idol down to rest and when he tried to lift it up again the idol did not budge. The Lord expressed his desire to stay near the Cauvery River and that he would be facing south, the direction to which Lanka is located.
