In the foreword to this book, the noted scholar of Tibetan Buddhism, Dr. Herbert Guenther, comments that this book “may well mark a breakthrough long expected and long overdue.” There is also a short introduction by Stanley Krippner of the Humanistic Psychology Institute. Swami Sivananda Radha, the author, founded and now directs Yasodhara Ashram, a yoga retreat and study center located on Kootenay Bay in British Columbia. She was a disciple of the famous Swami Sivananda Saraswati. This book is an extremely important contribution to the literature on kundalini yoga, a topic which in the West has too often been associated with the occult, esoteric, and therefore is “clouded in mystery.”
