One of the alvars, he was born into a Brahmin family in Shrivilliputhur, near Madurai in the 6th or 9th century (conflicting reports) CE and was named Vishnuchittar meaning "one who has Vishnu in his mind". Legend says he rejected the vedic philosophical debates of his upbringing to focus on Bhakti, especially on doing simple tasks for God. He would make garlands of flowers for the Deity of the Temple. One day the Pandyan king of the land had a competition between scholars to find one who would explain philosophical principles. Vishnuchittar won the competition by explaining that the path to moksha is by service to God. Legend goes that the king honored Vishnuchittar and God Himself came down to earth to see this.  Vishnuchittar composed some pasurams in the 4000 Divya Prabhandham called Perialvar Tirumozhi where he explores a Devotee's love for God through the metaphor of Yashoda's motherly love for Krishna. He was the adopted father of Kodhai or Andal, the only woman alvar.
