"The converts not only cannot participate in dances and folk songs, of the Hindu Tribals but also they are forbidden to sing among themselves their traditional folk songs. For this purpose, the missions have brought about changes in the mode of dances and introduced their own ideas in the folk songs which converts can play and sing. While the Hindu tribals dance and sing in the villages, the converts have to do it in the Mission or Church premises only."
