The Baul are a group of mystic minstrels of mixed elements of Vaishnavism and Tantra from different parts of Bengal such as Bangladesh and the neighboring Indian states of West Bengal, Tripura and Assam's Barak Valley and Meghalaya. Bauls constitute both a syncretic religious sect of troubadours and a musical tradition. Bauls are a very heterogeneous group, with many sects, but their membership mainly consists of Vaishnava Hindus and Sufi Muslims. They can often be identified by their distinctive clothes and musical instruments. Lalon Shah is regarded as the most celebrated Baul saint in history.

Lalon, also known as Lalon Shah, Lalon Fakir, Shahji and titled Fakir, Shah, was a prominent Bengali spiritual leader, philosopher, mystic poet and social reformer born in Jhenaidah, Bengal Subah. Regarded as an icon of Bengali culture, he inspired and influenced many philosophers, poets and social thinkers including Rabindranath Tagore, Kazi Nazrul Islam and Allen Ginsberg. Lalon's philosophy of humanity rejects all distinctions of caste, class, and creed and takes stand against theological conflicts and racism. It denies all worldly affairs in search of the soul and embodied the socially transformative role of sub-continental Bhakti and Sufism.
