Khenpo Jigme Phuntsok Rinpoche
(1932-2004) was a highly accomplished and respected Nyingma-school Dzogchen Master and Terton (Guru Rinpoche treasury discoverer/revealer). He was an incarnation of Dorje Dudjom, Guru Rinpoche's 24th disciple.
He helped spread and sustain Buddhism in Tibet -- especially when circumstances were not conducive as such.
