"Remarkable ethnography. Collaborative research at its best. The text builds on multiple shifts in perspective, moving between shamans and their patients, cosmology and political economy, shamanism as belief system and shamanism as business. The result is one of the most comprehensive, richly nuanced studies in ethnomedical literature. This is an excellent text for teaching shamanism in medical anthropology courses. The clarity of writing and the authors' skill in presenting sophisticated ideas in an engaging manner make it useful at both undergraduate and graduate levels. It offers a wealth of information for specialists interested in ethnomedicine, cosmology, and ritual."—Medical Anthropology Quarterly
