"Gurus of Modern Yoga offers needed treatments of contemporary figures whose current popularity far exceeds existing scholarly work on them-including Swami Ramdev, Sri Ravi Shankar, and Jaggi Vasudev-as well as several chapters on Krishnamacharya and his heirs."--Philip Deslippe, Nova Religio

"This fascinating collection of essays records the historical and sociological developments within particular yoga communities impacted by modernity, globalism, consumerism, competition, and technology...It is a rich contribution to the field. Recommended." --CHOICE

"Mark Singleton and Ellen Goldberg have put together an enlightening survey of the leading yoga gurus from around the world within the Hindu diaspora." --Spirituality Practice

"Mark Singleton and Ellen Goldberg have assembled a group of essays that combine critical rigor with sympathetic insight, including many by authors with extensive personal background in the practice of yoga. It is a welcome development that the scholar-practitioner model is becoming an accepted part of the study of Indian religions. This excellent book will likely become the go-to resource for the study of modern gurus and guru-based movements." --Andrew J. Nicholson, Stony Brook University

"This is a well-organized volume and a great resource. The essays present interesting biographies and fascinating developments of a worldwide spiritual industry that in the U.S. alone has an annual sale of supposedly more than $27 billion." --Numen
