Book excerpt: This is an essential work of Tibetan Buddhist thought written by an influential scholar of the twentieth century. From the same Nyingma school as the great Tibetan philosopher Mipam, Botrul in this text provides a systematic overview of Mipam's teachings on the Middle Way. Presenting the Nyingma tradition within a rich constellation of diverse perspectives, Botrul contrasts Nyingma views point-by-point with positions held by other Tibetan schools. Botrul's work addresses a wide range of complex topics in Buddhist doctrine in a beautifully structured composition in verse and prose. Notably, Botrul sheds light on the elusive meaning of "emptiness" and presents an interpretation that is unique to his Nyingma school. Distinguishing the Views and Philosophies exemplifies the vigorous tradition of Tibetan Buddhist scholarship and is widely studied in the contemporary monastic colleges of Tibet, India, and Nepal. Douglas Samuel Duckworth's translation will make this work widely available in English for the first time, and his thoughtful commentary will provide insight and context for readers.
