This book is an excellent introduction to the views of Theosophy, which in many respects is not a religion or a philsophy; it is a helpful guide to distinguish and compare theosophy both to the world religions as they are practiced and the "secret wisdom" that is also found in all world religions. As another reviewer remarked, the Glossary is a very helpful set of definitions for learning further about the theosophical perspective.
This is a great book that I am studying in a study group. This particular printing, ISBN-10: 1484839404, ISBN-13: 978-1484839409, the blue cover w/ the Mandala, is not a good printing. It has ONLY the main text of the book; No cover page, no copyright page, no table of contents, no glossary, no index, nothing.
This book gives a very nice introduction to the Theosophical movement.
Theosophy, to me, is a religious focus that does NOT disagree with any religion, but which is, to me, a way to think about God in ways that extend beyond any normal or regular system of faith.
Years ago, my Dad was into Theosophy, and I attended some of the conferences at a regional park. (I crashed the program, not paying an entrance fee, and they acted as if I was a full member. They were more interested in my attending than they were in getting a few dollars in the pot. (It helped that I lived a mile away at the time and got free meals from the people who ran the conference center where they shared meals, so it didn't cost them anything.)
If you enjoy studying alternate religious points of view, get this book.
Like I said, the only thing that keeps me from giving it a top rating is that it is written at a very high reading level, NOT like USA TODAY which is written at an eighth grade reading level.
