A Series of Lessons in Raja Yoga

William Walker Atkinson was an attorney, merchant, publisher, and author, as well as an occultist and an American pioneer of the New Thought movement. Atkinson was a prolific writer, and his many books achieved wide circulation among New Thought devotees and occult practitioners. He published under several pen names, including Magus Incognito, Theodore Sheldon, Theron Q. Dumont, Swami Panchadasi, Yogi Ramacharaka, Swami Bhakta Vishita, and probably other names not identified at present. He is also popularly held to be one (if not all) of the Three Initiates who anonymously authored The Kybalion. His work primarily focused on occultism, divination, psychic reality, and mankind's nature, or, what Atkinson called: "New Psychology" or "New Thought". Titles include Thought Vibration or the Law of Attraction in the Thought World, and Practical Psychomancy and Crystal Gazing: A Course of Lessons on the Psychic Phenomena of Distant Sensing, Clairvoyance, Psychometry, and Crystal Gazing.
