This paper explores a pilgrimage the author undertook with a group of pilgrims to the Bhuban cave in Assam, the assumed starting point of a religious reform movement known as the Heraka. He examines the interaction of the Heraka with different religious groups in the Bhuban cave (various ‘Hindus’, and indigenous religions). Dr. Longkumer is particularly interested in how different communities reify religious identification to the extent that other identities of shared interests attenuate, especially evident in the main ‘cave ritual’. Such encounters, he argues, not only sharpen Heraka identity vis-à-vis other communities, but also emphasise religious boundaries more generally. Such incidents can be read as a complex confluence of reform, intuition, experience and history. Dr. Arkotong Longkumer is a Departmental Lecturer in the Study of Religions at Oxford University. His research interests revolve around the anthropology of religion and history, with a south/southeast Asian focus. He has conducted fieldwork amongst the Nagas of India since 2005 and is currently interested in Naga nationalism, particularly the interaction between religion, nationalism and indigeneity.
