This paper aims to reinterpret the state religion of Manipur. It involves discovering how the various beliefs of the heterogeneous populations of Manipur were assimilated into the neutralized belief system coined as Umanglaism towards the creation of a socially integrated national community and how the influences from Mahayana Buddhism and Bhakti movement led to the development of two branches of Umanglaism, viz. Sanamahism and Bhagyachandra school respectively and how these two branches enhanced the idealistic doctrines of the ruling class to serve as reactionary purposes to sustain its position of privilege. This has been done by examining the backgrounds of various Umang lais (Umang gods) and the myths associated with them. This paper attempts to show that Umanglaism survives up to the present day through syncretism, dynamic translation, absorption and synthesis.
