Schul B., Pettit E. The Secret Power of Pyramids

USA: Fawcett Publ., 1975. — 224 p. — ISBN: 0340210125.Paranormal
Astounding new discoveries about pyramids and how they can change your life. One of the best of the pyramidbooks."This book is like the Rosetta Stone for my research for it provided enough of the information I needed to unravel the mystery I was working on. How could dirty water placed inside a cardbord model of the Cheops pyramid at the position corresponding to the King's Chamber with the pyramid oriented along a north-south direction become purified after two weeks while a similar sample of water left outside the pyramid remained cloudy? This was the key. Once I was able to figure that one out, I could see how it solved all kinds of other long-standing mysteries from the Backster effect, acupuncture, auras, fire, fluid turbulence and much more." - by Richard H.
