This is probably one of the most amazing books I've ever read. But don'e be fooled by the editorial review, it has nothing to do with the art of war. Written by someone completely different for a completely different reason, anyone who buys it looking for another Art of War will be sorely disappointed, as the person from Mass. was. If you are looking for a book about harmony, this is it. If you practice Aikido, this book is essential. Not only does it describe the way one should preform Aikido, it also shares deep insight into how to live in harmony with everything around you.
