Buddha Nature: The Mahayana Uttaratantra Shastra With Commentary is the fruit of twenty years of study by Rosemarie Fuchs, a member of the Marpa Translation Committee. A devoted student of the very Venerable Khenpo Tsultrim Gyamtso Rinpoche since 1978, Fuchs translated the text upon Khen Rinpoche’s advice. She also translated The Third Karmapa's Mahamudra Prayer.
