Once Pooratam Thirunal Thampuran, the
Brahmin ruler of Champakasseri (which was a small principality now known as Ambalapuzha)
was travelling in boat accompanied by sage Vilwamangalam Swamiyar. They suddenly heard
themelodious strains of the flute. The music emanated from the southeast corner of the
present temple at Ambalapuzha, where a peepal tree stands. The sage, the ardent devotee
that he was of Krishna, at once recognized that the music was that of the Lord. Therefore
he and the ruler got down, circumambulated the tree and prostrated themselves before it.
