Documented: Atkinson, 1862-1932, practiced law in Pennsylvania and Chicago, suffered a collapse he credited New Thought with curing, and turned to writing full time, producing The Kybalion (1908), the Ramacharaka yoga manuals, the Dumont success books, and Thought Vibration (1906), an early law-of-attraction text. Deslippe's research fixed the Kybalion attribution; the pseudonyms, the imprint, and the volume are matters of publishing record.
The folk reading is affectionate: Atkinson didn't fake gurus so much as manufacture the shelf a seeker needed, yoga from Ramacharaka, magnetism from Dumont, Hermeticism from the Initiates, one man running an entire mystery school out of a Chicago office. Critics answer that the device systematically laundered modern ideas into ancient authority, and the law of attraction is the proof: a 1906 sales technique retroactively eternal.
The claim: Atkinson is the cleanest documented case of tulpa economics, the Three Initiates and Ramacharaka functioning as egregores, entities made of attention, authored into existence, still signing books a century later. If entities made of attention are real in any sense, he is the century's most successful summoner.
Does it matter that the ancient masters were one lawyer with a mailing address?
