In Tibetan Buddhism, there is a type of teaching called a dmar khrid, a ''red instruction,'' wherein the lama brings students through a teaching as a physician might dissect a corpse, pointing out and explaining the various parts and organs and their places and functions. In Identity, Ritual and State in Tibetan Buddhism, Martin Mills has done very much the same thing, with the exception that the body he examines is still very much alive, and emerges, to my eyes at least, as a new and wholly vital entity. Mills exposes the subcutaneous and sanguine body of Tibetan Buddhism, the bones and muscles that make up its structure, the blood that flows through it, and the organs that keep it alive, in ''a plain and open manner,'' just as in a dmar khrid. 1 The value of such a presentation truly cannot be overstated. An attempt to catalog the contents of each chapter would be both impossible and counterproductive, as the wealth of theoretical material and ethnographic detail is a large part of what makes this book so powerful. Instead, I will identify several topics, several of the vital organs alluded to, that are either not commonly noticed in the academic study of Buddhism, or that are given fresh perspective by Mills's anthropological and sociological methodology, and that are so crucial to understanding how it is that Buddhism lives in a typical Himalayan village. The latter portion of this review explains why I place such high value on this book and its potential place in Buddhist-Christian studies. Identity, Ritual and State is an ethnography of Kumbum Monastery in Lingshed, Ladakh (the eastern half of the Kashmir valley, located in Jammu and Kashmir, India), but its concerns are much more far-reaching than a single remote Himalayan village. The central question of the work is ''how we are to understand the nature of religious authority in Tibetan Buddhist monasticism'' (p. xiii), although it might more properly be the religious authority of Tibetan Buddhist-Christian Studies 27 (2007).
