Hello, bodhimind, and thank-you for posting Blavatsky's Meditation Diagram. The thing that always bothered me about the work of Blavatsky and others at the Theosophical Society, is it is just much too cognitive; relying too much upon the mental projection, with no understanding of the subjective quality of the altered state of consciousness that is a key part of the 8 stages of the religious experience (samadhi). So, What I see in Blavatsky's Meditation Diagram is she got most of it out of flawed translations of the suttas, which began around the middle of the 19th century.
It is worth noting that the history of recent Buddhism, and translations of Buddhist literature; and for that matter almost all other translations of Asian philosophy, were mostly funded, or done by, members of the Theosophical Society; which I believe explains why nearly all translations of Asian philosophy are so deeply flawed.
Please note: Since we have started a new section for Western Occult literature, then I thought it best to move this thread there.
