Synopsis The Barak Valley of Assam is a less known region with some features quite distinctive and unique. Though within the political map of Assam, geographically the region is a natural extension of the reverine Bengal and in a sense it demarcates the frontiers between the plains of the gangetic basin and the hilly uplands of the north-eastern India. Culturally the zone forms to easternmost outpost of the Aryanised India where the Brahmanical Hinduism alongwith Sanskrit language penetrated in early Christian era. At the same time, its encounter with the Buddhism and the Islam can be traced back to the A.D. seventh century and fourteenth century respectively. This, coupled with its proximity to the hills where different tribes have been living from time immemorial with their indigenous ways of life, makes the region a fertile ground for productive interaction between cultures and traditions of various shades and genre. The folk cults of the valley retains deep imprints of this prolonged and poly-dimensional process of cultural interaction.
