Biography of Kunzang Dorje Rinpoche

"Kunzang Dorje Rinpoche is one of the greatest living yogis from the Nyingmapa tradition. His life story is an example of the lives of the great Mahasiddhas of the past, eschewing the worldly trappings of modern-day life and wandering homelessly from holy place to holy place, dedicating his life to the hardships of continual practice and retreats."
