The present essay, which is based on research carried out in the Rarh area of West Bengal, offers an overview of the ritual language of the Dharma Thakur cult. From the liturgical texts of Dharma-ism, namely Sunya Purana and Dharma-puja-vidhana, to the live religious performances, the author presents the evolution process of a language that has basically survived as 'mantric' in its purposes and meanings. On the basis of his translation of Sunya Purana and interviews with Dharma-pandits, the author analyzes some of the mantras still used and their significance; the author investigates why neither priests nor devotees care about knowing their meaning, why a translation is not felt to be necessary and what 'the word' represents in Dharma ritualism.
