Once every few years you come across a book which is genuinely life-changing, and this is one of them. In its simplest form it's a book which makes numbers interesting - completely different from the usual dull stuff you did at school. But it goes way beyond that, to open up a whole world of cosmic geometry which you'd never noticed before. It explains the principles of number and sacred geometry with extraordinary clarity and applies them to architecture, religion, ancient art, modern design, science, the natural world, etc, on the basis that all forms of construction and creation work on those same principles. It covers everything, from the reason why manhole covers are round to the divine emanations of the Qabalah, and links the physical with the spiritual in ways you would never have thought of. The book has a wide format and very clear layout, with lots of illustrations, and assumes no previous knowledge of - or interest in - the subject.
I notice in Mr Schneider's comments that it took him 20 years to research the book. Well, it certainly shows, and I can assure him it was very well worth it. This is truly a revelation, an amazing book which will completely change the way you look at the world.
