As the book says on its cover, it is intended to be a resource similar to Crowley's 777. However, this book takes that format to a 'new level.' It is safe to say that, if you are a magickian of any level, you will find useful information in these pages. I was surprised to find so many correspondences for Kabbalah, for Alchemy, for the Tarot, and for Angelic (and Demonic) magick.
The book is laid out in logical, alphabetically arranged tables for just about every subject a magickian needs. The correspondences are based on the '32 Path' layout used in 777, but the resemblance to that work ends there. The author has done an incredible amount of research so you won't have to. Just look up the subject and you will find a treasure-trove of useful information.
You may not know it, but you need this resource. You won't be sorry you bought it !
Peace Profound,
