Biographie de William Walker Atkinson
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 converted to any form of Hindu religion, or merely wished to write on the subject. If he did convert, he left no record of the event.
According to unverifiable sources, while Atkinson was in Chicago at the World's Columbian Exposition in 1893, he met one Baba Bharata, a pupil of the late Indian mystic Yogi Ramacharaka (1799 - c.1893).
As the story goes, Bharata had become acquainted with Atkinson's writings after arriving in America, the two men shared similar ideas, and so they decided to collaborate.
