In my search to understand the Tarot, I have read probably 25 books or so. Some of them, a very few, stand out as what I consider to be the best. Coming to grips with the Tarot is very personal, but I'm a traditionalist in the sense that earlier decks tell more about the original intent, and that there is a structure to the major and minor arcana; there for the Diviner to construct a methodology.
This particular book by Alfred Douglas is right on the mark, and his analysis and interpretations have added knowledge to my extensive readings. In short- a fabulous top of the line Tarot book (Barbara Walker also comes to mind) for not only the beginner (what a great place to start!) but also for the advancing. While not complicated in the least, his interpretations are thought-provoking, and expansive.
