* Hatha yoga is commonly thought to be a pure, ancient Indian spiritual discipline that transcends cultural, temporal and spatial boundaries or a spiritual discipline corrupted by Indians (for export) or Westerners (for import) to accommodate Westerners. Calling these beliefs into question, Max Popov's Radiant Bodies shows how hatha yoga was transformed from sacred practice into a health and fitness regime for middle-class Indians in India in the early and mid-20th century. Popov tells the story of this transformation through the lives and accomplishments of eleven key figures: six Indian yogis (Shri Yogendra, Swami Kuvalayananda, S. Sundaram, T. Krishnamacharya, Swami Sivananda and B. K. S. Iyengar), an Indian bodybuilder (K. V. Iyer), a rajah (Bhavanarao Shrinivasrao), an Indian diplomat (Apa Pant), an American-born English journalist (Louise Morgan), and a Russian-born yogi trained in India (Indra Devi).Their accomplishments are placed within the context of such Western trends as the physical culture movement, the commodification of exercise, militant nationalism, post-World War I anxiety, the mystique of science, jazz age popular entertainment, and the quest for youth and beauty. Through a series of biographical narratives placed in a rich cultural context, Popov not only brings to life the formation of modern hatha yoga as an exercise system in the early 20th century but also its transformation over the course of the 20th century into an embodied spiritual practice. Popov draws on extensive research from rare primary sources to present a cutting edge interpretation of the history of modern hatha yoga. Radiant Bodies is a thoughtful book for the educated general reader that would also be of special interest for religion scholars and yoga professionals and practitioners
