"An impressive translation of a fascinating and vitally important book. This will be of great interest to students of Tibetan Buddhism. Its broad scope and keen observation makes it an invaluable resource. And for scholars interested in the history of comparative religion, it shows how sophisticated, eighteenth-century Tibetan Buddhists could come to terms with diverse world religious traditions."

– Guy Newland, Central Michigan University, author of Introduction to Emptiness

"Thuken's Crystal Mirror of Philosophical Systems is a unique work, seeking to document the full range of philosophical traditions known in Tibet, including Indian, Chinese and, above all, indigenous Tibetan traditions. This translation is precise and a pleasure to read."

– Matthew T. Kapstein, Ecole Pratique des Hautes Etudes and the University of Chicago, editor of Buddhism Between Tibet and China

"This notable work, completed at the beginning of the nineteenth century, presents an in-depth treatment of the key schools of Tibetan Buddhism--Nyingma, Kadam, Sakya, Kagyu, Gelug, and Jonang, as well as Bon. The reader-friendly translations introduce the texts to the general reader, making this a valuable contribution to our understanding of the richness of Tibetan Buddhism."
