One of the foremost texts of all Theosophy, "Initiation Human and Solar" is a lengthy work by the highly noted Alice Bailey, containing numerous (and usually categorical) sections of hierarchies involved with the process of the initiate joining the order, being refined through time, and learning about various occult secrets and powers.Some of the content here is quite dense and so a short glossary has been added by the author which helps to explain a few of the eastern (or, in some cases, new age!) terms used.
