Fundamentals of Theosophy

I was somewhat surprised by this book, "Fundamentals of the Esoteric Sciences" by Manly P Hall. The author was a well known American esotericist.

I assumed that his message was some kind of Hermetic-inspired Masonry. Judging by this work, however, Hall's ideas were derived from Theosophy. Indeed, they *are* Theosophy. The messages are virtually identical: mystery religions, cosmic evolution, root-races, Mahatmas, even the sunken continents of Atlantis and Lemuria!

I'm not sure why Hall didn't simply join one of the main branches of Theosophy. Perhaps he couldn't stand Tingley or the Besant-Leadbeater-Krishnamurti axis?

Hall's book could be considered an introduction, in question and answer format, to the fundamentals of...Theosophy.
