The author of Sri Krishna Karnamrutham is Bilva Mangala. He belonged to a place called Mukkutalai, originally mukti-sthalam, in kerala. He came to be known as Leela Shuka. Leelasuka belonged to a saivite family by tradition. But he became a devotee of Krishna. Hence he refers to his traditional background by saying that he wears the feet of Lord Siva on his head. He belongs to the tradition of great devotees of Krishna of Kerala such as Narayana Bhattatiri, the author of Sri NarayaNeeyam, Poonthaanam and Vasudeva Namboodiri and other great scholars of Dasama skhandham of Srimad Bhagavatham.
In his early life, he was very fond of a Deva Daasi by the name Chintamani. She teased him once about his scholarship in Vyaakaranam, Naatakam and Alankaara Saastram and told him that if he had one thousandth of the affection for Bhagavaan, he would easily save his life. That was the turning point for Bilva Mangala. He thanked Lord Krishna for showing the true destiny of his life.
