The book starts with his examination into the background, and possible historical uses of the famous Mitchell-Hedges crystal skull, which he studied for six years. He is the one who brought the skull to the Hewlett-Packard lab to be studied. He documented his efforts and observations and it makes interesting reading. This led him to close his successful business and devote his time to researching the historic and traditional uses of electronic quartz crystals. What stands out for me, is how he ties traditional, shamanic / magical practices in with the modern 'scientific' usage of quartz in electronic devices, etc. He paints a convincing picture for there being a logical reason, (and not just superstition or placebo effect) why specific types of crystals have consistently been used the world over by 'healers and adepts' for augmenting and accelerating the effects of healing, meditative states, etc. If you have an open mind, but don't buy every idea that comes 'from the ethers' as being valid, this book will appeal to you. He makes a good case for all but the most dedicated of skeptics to take another look at how quartz crystals can be useful. For those people who already use crystals or are interested in possible 'metaphysical' properties this is a must read for anyone of rock quartz. You may learn a thing or two.

Finally an actual book without mumbo jumbo on ROCK CRYSTAL. How to use it and why it works.
Photos, examples and how to acquire one of the crystal carvings.

I have read it several times and find something new each time.

A touch of Mysticism with alot of fact should be the way a book is written on such an important subject.
