Rosemary Patton began studying Tibetan Buddhism and language in France with Dagpo Rinpoch� in 1975 after earning a degree in English literature and drama at Queen's University in Canada and a degree in anthropology at the Sorbonne. After attaining a further degree at the Institut national des langues et civilisations orientales (INaLCO) in Paris, she pursued her studies at Drepung Gomang in South India.

Dagpo Rinpoch� was born in Kongpo in southeastern Tibet in 1932, was recognized as an incarnate lama at age one by the Thirteenth Dalai Lama, and trained as a monk at Dakpo Shedrup Ling and at Drepung Monastery's Gomang College in Lhasa. After the Communist takeover of Tibet in 1959, he crossed the Himalayas on foot, and the next year he emigrated to Paris, where he worked with scholars and taught at INaLCO until 1993. In 1978 he founded his first Dharma center, which in 1994 became the Ganden Ling Institute. He has traveled extensively, guiding students and creating numerous centers for the study and practice of Buddhism around the world.
