Thondaradippodi Alvar or Vipra Narayana was one of the twelve Alvar saints of South India, who are known for their affiliation to Vaishnava tradition of Hinduism. The verses of Alvars are compiled as Naalayira Divya Prabandham and the 108 temples revered are classified as Divya desam. Thondaripodi is considered the tenth in the line of the twelve Alvars. As per Hindu legend, he was born as Vipra Narayana and got devoted to Ranganatha of the Srirangam Ranganathaswamy temple. Since he worshipped even the dust from the devotees of Ranganatha, he attained the name Thondaradipodi. His works are the Tiruppallieluchi having ten verses, and Tirumālai having forty verses, both of which are counted among the 4000 stanzas in the Naalayira Divya Prabandam. The works of Thondaradipodi and other Alvars contributed to the philosophical and theological ideas of Vaishnavism. Along with the three Saiva nayanmars, they influenced the ruling Pallava kings of the South Indian region, resulting in changing the religious geography from Buddhism and Jainism to the two sects of Hinduism. In South-Indian Vishnu temples, Thondaradipodi Alvar has images and festivals associated with him. The Vasantha Utsavam festival is celebrated in Srirangam and for nine days in the garden believed to have been maintained by him. The verses of Thondaripodi and other Alvars are recited as a part of daily prayers and during festive occasions in most Vishnu temples in South India. Alvars The word Alvar means the one who dives deep into the ocean of the countless attributes of God. Alvars are considered the twelve supreme devotees of Vishnu, who were instrumental in popularising Vaishnavism during the 5th to 8th centuries CE. The religious works of these saints in Tamil, songs of love and devotion, are compiled as Nalayira Divya Prabandham containing 4000 verses and the 108 temples revered in their songs are classified as Divya desam.
