We understand and experience so little of what is actually going on in our world. When I first read Dowsing The Ultimate Guide for the 20th Century, there were parts, for example where Elizabeth discusses scientific concepts, particularly those relating to the science of Quantum Physics which I found challenging, other parts which I found excitingly familiar. The chapter entitled Preparation for Dowsing is inspired. After reading through the book a few more times...I can say that there is not a single bit of the book that I don't understand...rather, the more times that I read it, the more I discover...thank you so much Elizabeth Brown for writing the most inspiring, heart opening, mind blowing piece of non fiction which I never tire of reading. No words of mine can represent the clarity of her understanding and of her writing.
