Query: Book Shelf must have

This book works! When something is out of sync....family, work, money I open up my book and make a few adjustments! I sware it works! I've given 4 copies away as gifts thats how awesome this book is. I believe it is a must have. If your looking for a college degree in Feng Shui this is not it. If you want to put the idea's to work in your everyday life this book is it.
