A Tamil Veda for Sri Vaishnavites - Sri Vaishnavas consider Nalaayira Divyaprabandham as holy as Vedas and they call it as Tamil Veda. Over a period time all the hymns sung by all the 12 Azhwars were lost. One fine day, when Saint Nadhamunigal were worshipping the Almighty at Thirukkudanthai Divyadesam in Kumbakonam, he had a chance to hear some of the pasurams starting with “Aaraa Amudhe“ by some devotees . He was very much attracted by those pasurams. He asked the devotee abot the rest of pasurams but he had no idea about and he was knowing only few that too not even grouped. Nadhamunigal had a thrust to collect all the pasurams and started searching for. He then heard that descendants of Madhurakavi Azhwar were having some hymns. He went all te way to Thirukkovilur and collected those hymns starting with “Kanninum Sirithambu”. At that time Nammazhwar appeared before him as a old man. He tested Nadhamuni vigorously. Finally he got pleased about the devotion he was having and gave the pasurams to him, which were then compiled into one as “Nalayira Divyaprabandham” in which Alwars praised, described and worshipped the Almighty as a baby, friend, servant and even as a consort.
