Divya Desams refer to the 108 Vishnu temples that are mentioned in the works of the Tamil Azhvars (saints). Divya in the Tamil language indicates "premium" and Desam indicates "place" (temple). Of the 108 temples, 105 are located in India, one in Nepal and two outside of the Earthly realms. Most of the Divya Desams in Tamil Nadu follow the Thenkalai tradition. This includes the important temples of Srirangam and Triplicane.
The Divya Desams are revered by the 12 Azhvars in the Divya Prabandha, a collection of 4,000 Tamil verses. Lord Shiva, the other major deity in Hinduism, is similarly associated with the Paadal Petra Sthalams, 275 Shiva temples which are praised in the Tevaram canon by the 63 Nayanars.
