What can I possibly say about this little gem of a book? You can sit down and read the whole thing in an afternoon - highly recommended just for the entertainment value - and then you can spend a few years working your way through the exercises. If you work with the exercises - the only way you'll really understand this, even if you've practiced other forms of magick or meditation before - you will continue to astound yourself with your own ability to grow and change and expand your consciousness. Phil Farber's concept of ritual as the art of set and setting makes this material useful in so many situations that, well, it's just incredibly useful!! This book should be part of every magick library, on the shelves along with Crowley, Regardie, and Carroll.
