Manly P. Hall - The Secret Teachings of All Ages

Each of the nearly 50 chapters is so dense with information that it is the equivalent of an entire short book. If you read this book in its entirety you will be in a good position to dive into subjects such as the Qabbala, Alchemy, Tarot, Ceremonial Magic, Neo-Platonic Philosophy, Mystery Religions, and the theory of Rosicrucianism and Freemasonry. Although there are some questionable and controversial parts of the book, such as the outdated material on Islam, the portion on the Bacon-Shakespeare hypothesis, and Hall's conspiracy theory of history as driven by an elite cabal of roving immortals, they are farout-weighed by the comprehensive information here on other subjects.

I knew someone with that book and had glances at it. It is very good book. A bit dense to read as there is a lot in it. The kid with the book flailed, couldn't be bothered carrying it around so now it is probably rotting somewhere.

The stuff in there about Atlantis is very interesting.
