Periazhwar obtained the name as he is believed to be an ardent worshipper of Vishnu. While coming out of Madurai, he was taken out in procession to Srivilliputhur and he got the divine vision of Vishnu at the instance. He started reciting his composition, Periya Thirumozhi, which was compiled in Nalayira Divya Prabhandam by Manavala Mamunigal. Manavala decreed that the verses of Perizhwar starting with Tirupallandu should be the first and last verse while reciting Pradandam in any sacred occasion in Vishnu temples. Ramanuja, a proponent during the 10th century, believes that Tirupallandu originated at Madurai. Thus Koodal Azhagar temple finds an indomitable position in Vaishnavite belief.
