Crystalline structures are defined by their regular shape. A crude example would be that the difference between a pile of sand (also mostly quartz) and a quartz crystal, is that in the crystal the silicon and oxygen molecules are arranged in a mathematically precise, rigid structure. This geometric precision and harmony has been investigated and utilised by many cultures, most famously, the ancient Egyptians. 

The seventh wonder of the ancient world, the Great Pyramid at Giza is a triumph of engineering that cannot be repeated with any number of computer-aided graphics or massive machinery. Max Toth and Greg Nielsen, in Pyramid Power say, "There is no doubt that every civilisation which built pyramids did so with the use of highly advanced mathematical and astronomical calculations and a seemingly impossible mastery of the skill of stone masonry. In civilisations separated not only by thousands of miles but also by thousands of years, stones weighing many tons were hoisted into position with infinite precision. So great was the engineering agility and skill required to manoeuvre the huge granite blocks into place that how it was accomplished still remains a mystery.”

The most extraordinary feat of engineering was that of the cutting and placement of the highly polished limestone casing stones that covered the entire pyramid. The finished pyramid contained approximately 115,000 of these stones, each weighing ten tons or more. These stones were dressed on all six of their sides, not just the side exposed to the visible surface, to tolerances of .01 inch. They are set together so closely that a thin razor blade cannot be inserted between the stones. Egyptologist Petrie expressed his astonishment of this feat.

The purpose of all this precision and unquantifiable amount of work was to one end,
to incorporate a ratio. No more, no less.

What effect this ratio has on the body, mind and consciousness is another vast subject, but the fact remains..... every angle and measurement the Great Pyramid reflects the mathematical proportion that has been contemplated and utilised by seers for thousands of years

..... phi, Ф, the Divine Proportion, 1.618.

The Great Pyramids height is the square root of the golden section (1,272) and its slant is the golden section (1.618) if the base is considered 1. The Kings Chambers is 10.46 meters East to West, 5.23 meters North to South and 5.81 meters high, thus perfectly reflects phi.
 

The old crystal radios showed the ability of quartz to receive and transmit energy, in this case radio waves. This has been utilised by mystics and the electronics industry alike.

Although much research remains to be done in the areas of archaeology, mathematics and earth sciences, much evidence now exists that appears to indicate that the Great Pyramid was a monumental device for gathering, amplifying, and focusing a transformative energy field. What is known is that this energy field acts in powerful ways. A dead mouse is dehydrated and preserved perfectly, even in high humidity. The crystalline structured edge of the razorblade is re-aligned to give a sharp edge and the adept is re-aligned with Divine order.
