point of his prodigious capacity for production was reached in the late 1910s. In addition to writing and publishing a steady stream of books and pamphlets, Atkinson started writing articles for Elizabeth Towne's New Thought magazine Nautilus, as early as November 1912, while from 1916 to 1919, he simultaneously edited his own journal Advanced Thought. During this same period he also found time to assume the role of the honorary president of the International New Thought Alliance. Among the last collaborators with whom Atkinson may have been associated was the mentalist C. Alexander, "The Crystal Seer," whose New Thought booklet of affirmative prayer, "Personal Lessons, Codes, and Instructions for Members of the Crystal Silence League", published in Los Angeles during the 1920s, contained on its last page an advertisement for an extensive list of books by Atkinson, Dumont, Ramacharaka, Vishita, and Atkinson's collaborator, the occultist L. W. de Laurence. Atkinson died November 22, 1932 in Los Angeles, California at the age of 69. Writings 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, which certainly resembles Atkinson's other writings in style and subject matter. Atkinson's two co-authors in the latter venture, if they even existed, are unknown, but speculation often includes names like Mabel Collins, Michael Whitty, Paul Foster Case, and Harriett Case. A major collection of Atkinson's works is among the holdings of a Brazilian organization called Circulo de Estudos Ramacháraca. According to this group, Atkinson has been identified as the author or co-author (with individuals such as Edward E. Beals and Lauron William de Laurence) of 105 separate titles. These can be broken down roughly into the following groups: Titles written under the name William Walker Atkinson These works treat themes related to the mental world, occultism, divination, psychic reality, and mankind's nature. They constitute a basis for 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, Crystal
