Once Lord Brahma ( the creator) thought that he is the sole reason for the world living beings being beautiful. Lord Vishnu advised to brahma but still his ego didn’t go. So Lord Vishnu cursed him to go to earth and take a birth of a normal human being. Lord Brahma who born as a human at earth went to many temples and worshipped to get rid of his curse.
At that time he saw a very handsome man who crossed him. Brahma thought that he never saw such a beauty. Later he realized that man was none other than Lord Vishnu, who came down to show him that the beauty is not stable and ego will demolish one’s life. As Lord Vishnu showed mercy on Brahma and showed his full form at this place, it is called as Anbil (Anbu means love in Tamil).
As per Hindu legend, sage Suthaba was doing penance at this place. He had to powers to reside both in water and land. He did not observe sage Durvasa , who was waiting for him. Durvasa got irritated and cursed Suthaba to become a frog called mandukam in Sanskrit . Suthaba requested Durvasa on the penance he had to do to get relieved off the curse . Durvasa explained him that the curse was on account of the sin he committed in his previous birth and Vishnu would appear to him to relieve him . Suthaba , as a frog , continued his penance under water in the Manduka Theertham in the temple and Vishnu appeared to him as Sundararajan . Hence, this place is called Manduka (Frog) Puri .
Thirumazhisai alwar has sung praising this Lord .
