These mystic minstrels include mixed elements of Sufism, Vaishnavism and Tantra to form the Baul group. Their philosophy transcends the traditional concept of religion and is critical of the superficiality of the division between different systems.
Purna Chandra Das made Baul songs known worldwide through his association with Mick Jagger, Bob Dylan, Mahalia Jackson and many more. It is an experience to listen to the songs at the Baul Akhras beside the Kopai River in Shantiniketan or the Shonajhuri Haat.
