The book is a sociological study of the resilience of Tingkao Ragwang Chapriak one of the indigenous religions of the Rongmei people of Manipur. It examines the underlying factors contributing towards the ability of the adherents of Tingkao Ragwang Chapriak to continue with their religion despite stigmatisation, conversion and persecution by sections of Christians. This book reflects the contemporary relevance of the legacies of the religious movements under Jadonang Malangmei and Rani Gaidinliu. Thus, the book also examines the continuity between the past and the present religious movements with complex underlying factors contributing to the resilience of an indigenous religion. The Rongmei people following Tingkao Ragwang Chapriak, a reformed religion, are seen to be not shying away from changes in their religious beliefs and practices. Interestingly, however, despite all the reformations consciously heralded the idea of primordiality in the sense of unchanging is a sincere atavism among the adherents of Tingkao Ragwang Chapriak. Methodologically speaking, the emphasis of the book is on theoretical and methodological triangulation. Both social change theory and social identity theory are used to understand the resilience of the indigenous faith of the Rongmei people a midst dominant Hindus and tribal Christians. It is observed that the idea of change is indispensable in understanding the resilience of an indigenous faith despite the commonly held belief in the essentiality of primordiality in a religion. The book is intended to serve the academic interests of researchers working on indigenous religions.
