Tri Ranga

River Cauvery has formed three big islands on her journey from Talacauvery to join the Bay of Bengal Sea. The islands are Srirangapatna, Shivanasamudra in Karnataka and Srirangam in Tamil Nadu. All the three islands are pilgrimage centers with temples dedicated to Lord Ranganatha. These three temples are known as

1. Adi Ranga/first Ranganatha at Srirangapatna,


2. Madhya Ranga/Middle Ranganatha at Shivanasamudra and


3. Anthya Ranga/Last Ranganatha at Srirangam.

It is believed that people who visit the three temples in one day gain moksha/Salvation.
