I take exception to much of the previous review ("Housewife's Magic"). It's important to read the title and understand that it's a workbook, and the word "work" describes the intent of the book very well. The central theme here is preparation for magic, by working. The cleaning, the building, the readings, the attention to the details of the magical implements ... they all serve the purpose of focusing energy/concentration and achieving the discipline needed to effect change through will. You've utterly missed the point if you think these are just a bunch of mundane details and are unimportant. They're the meat of the book, they ARE the real magic, and the heart of the discipline being taught here. The "followers of other magical paths" can bypass all that and skip to the sensation-seeking, but why bother with a book like this if you believe it's only the rituals themselves that matter?
I enjoyed it for the detail about the making of the implements and the temple. So it's practical, as described, but a fuller self-initiation requires several other books and thus the suggested readings at the ends of each chapter.
If you want to put your hands to meditative use so you are well-grounded for further explorations, then this is a marvelous introductory book.
