Sthala Puranam: Once there was a king named Swethan, the son of Thundu maran of the Surya dyansty. Fearing early death he sought the help of "Maruthuva Maharishi", the son of Lord Surya the sun god. He instructed swethan to chant the "Mrithyunjaya Manthiram" by sitting under the Tree vilvam which was on the south bank of the pushkarani. Lord Narayanan presented himself before the king and blessed him with a long life. This Kshetram is known as South Tirupathi. All the offering in due to the Thiruvenkadamudayan of Tirupathi can be offered here too. At Thiruvinnagar, Lord Oppiliappan blesses along with godess Bhoodevi as an equivalent form of Lord varahaswamy and Bhoodevi as Tirumala Tirupathi. Also as an equivalent form of Lord Srinivasa and Padmavathi Thaayar, the Lord blesses us as Thiruvellakulam as Lord Srinivasa and Padmavathi. As for the above stated reasons, both the Kshetrams are considered in equivalent with Tirumala Tirupathi. Sri Annanperumal is the elder brother of Lord Vendateswara of Thirumala. Hence, this temple is known as Annan Perumal Kovil As he saved the king Swethan from the death fear he shows himself as Varadharajan. So, the perumal stands as form representing all the yugams. the Vimaanam too has a hint of this act as Thathuva Yodhaga Vimaanam. Vellam means flood and kulam means pond. Both the terms represent water only. As like Annan Kovil, this place has got its another name "Thiru Vellakulam" from the above similarity. It can also taken that Lord Rama, Balarama and Aadhi vishnu are all of white colour. Lord Krishna is of Blue colour the colour of water in ponds and tanks. Taking Vellam as Vellai White colour it can also be said that the name Vellakulam was got by the above reason.
