Drs. C. Alexander and Annellen Simpkins live in San Diego and are both psychologists who have specialized in studies of the mind. They have devoted many years to the study of hypnosis and have taught meditation skills to people of all ages. They have also spent the past 25 years involved in the martial arts as practitioners, instructors, and writers. Their work in meditation spans their two worlds of professional interest: martial arts and psychology, adding a unique and comprehensive perspective to this book. In addition to contributing regularly to martial arts publications, they are the authors of "Principles of Meditation, Living Meditation, Zen Around the World," and "Meditation from Thought to Action," all published by Tuttle.
