This is a wonderful classic of hermetic qabalah, a must for anyone interested in magick. Dion Fortune was a great mystical and magickal writer and teacher, inspiring to this day. But this edition, published by the Fraternity Sanctum Regnum (FSR), is execrable, filled with typos and poor editing generally, with tiny characters. The only thing it's good for is scribbling notes all over the margins, which Dion Fortune's thoughts certainly inspire me to do. My advice - get a decent edition of this book, although if this is all you can find (as was my case at the time), then better a poor edition than having to do without the book altogether.
