The temple is counted as Vaishnava Sukra Kshetra as Vishnu appeared as a beautiful deity to please his devotee Sukra (Venus). The place derived its name Thiruvelliyangudi hence and the presiding deity is also referred to as Velliyan. It is believed that Vishnu appeared in Kalyana Kolam (marriage posture) to Parasarar, Markendeyar, Mayan, Brahma, Sukran and Bhudevi. To de-stress or relieve Lord Vishnu, his mount or vahana, the eagle Garuda, holds the conch and the Sudarshana Chakram or discuss|wheel of Vishnu which is very unique in nature, making this the only temple where Garuda is depicted in such a posture. Sage Parasarar is believed to have done penance in this temple and hence there is a temple tank called Parasara Theertham. A banana plant is seen growing from a granite base and it is believed to be historical. The temple is revered in Nalayira Divya Prabandham, the 7th-9th century Vaishnava canon, by Thirumangai Alvar in one hymn. The temple is classified as a Divyadesam, one of the 108 Vishnu temples that are mentioned in the book.
