He then met Sydney Flower, a well-known New Thought publisher and businessman, and teamed up with him. In December, 1901 he assumed editorship of Flower's popular New Thought magazine, a post which he held until 1905. During these years he built for himself an enduring place in the hearts of its readers. Article after article flowed from his pen. Meanwhile, he also founded his own Psychic Club and the Atkinson School of Mental Science. Both were located in the same building as Flower's Psychic Research and New Thought Publishing Company. Atkinson was a past president of the International New Thought Alliance. Publishing career and use of pseudonyms Throughout his subsequent career, Atkinson was thought to have written under many pseudonyms. It is not known whether he ever confirmed or denied authorship of these pseudonymous works, but all of the supposedly independent authors whose writings are now credited to Atkinson were linked to one another by virtue of the fact that their works were released by a series of publishing houses with shared addresses and they also wrote for a series of magazines with a shared roster of authors. Atkinson was the editor of all of those magazines and his pseudonymous authors acted first as contributors to the periodicals, and were then spun off into their own book-writing careers—with most of their books being released by Atkinson's own publishing houses. One key to unravelling this tangled web of pseudonyms is found in "Advanced Thought" magazine, billed as "A Journal of The New Thought, Practical Psychology, Yogi Philosophy, Constructive Occultism, Metaphysical Healing, Etc." This magazine, edited by Atkinson, advertised articles by Atkinson and Theron Q. Dumont—the latter two were later credited to Atkinson—and it had the same address as The Yogi Publishing Society, which published the works attributed to Yogi Ramacharaka. Advanced Thought magazine also carried articles by Swami Bhakta Vishita, but when it came time for Vishita's writings to be collected in book form, they were not published by the Yogi Publishing Society. Instead they were published by The Advanced Thought Publishing Co., the same house that brought out the Theron Q. Dumont books—and published Advanced Thought. Hinduism and yoga In the 1890s, Atkinson had become interested in Hinduism and after 1900 he devoted a great deal of effort to the diffusion of yoga and Oriental occultism in the West. It is unclear at this late date whether he actually ever
