Preliminary abstract: What is the relationship between institutional authority and religious power in Tibetan exile? My research focuses on how the charisma and legacy of Ngagpa Yeshe Dorje Rinpoche, the former official weather controller of the Tibetan exile government - are being institutionalized and mediated in exile following his death. Ngagpa (m) and ngagma (f), are non-celibate, professional Buddhist renouncers who specialize in esoteric ritual traditions. Simultaneously existing in and straddling lay and monastic worlds, they reside in a shifting third space of accommodation and resistance to mainstream structures. With the invasion of Tibet by China in 1950, Tibetan refugees in India have struggled to make a sovereign nation legible and legitimate in exile, and to rebuild political and social institutions away from home. The once de-centralized religious traditions of virtuoso ngagpa/mas are now being preserved in durable institutions, fixed in texts, and taught increasingly to foreigners. Researching Yeshe Dorje's institution in India and its resident ngagpa/mas, I examine how the politics of ritual power are playing out in exile communities. Using ngagpa/mas' charisma as a lens through which to explore unfolding politics of reform in diaspora, I show how the forging of cultural coherence in exile involves both creativity and contradiction.
