Explanation

Amritlal Vithaldas Thakkar, known as Thakkar Bapa, founded the Bhil Seva Mandal in 1922 to work for the welfare and education of the Bhil tribal communities of Gujarat and adjoining regions. Dayaram Gidumal founded the Seva Sadan, Dhondo Keshav Karve pioneered women's education and widow remarriage, and Gurusaday Dutt is associated with folk-culture revival. The Bhil Seva Mandal is specifically Thakkar's organisation.
