As we explore the ancient cultures and civilizations of the world, we find the Egyptians believed in the mystical powers of crystals and used them to heal many illnesses. They invented a system of how the color of the crystal corresponds to a certain energy center of the same color. The color of the body part and associated energy center was matched to the color of the gemstone. The Egyptian Royalty and high religious officials were usually buried with gemstones, crystals to guide them in the underworld. Katrina Raphaell says in her book “Crystal Enlightenment”, that, “Many deceased royalty were laid to rest with elaborate collections of gems and stones, when the tomb of King Tut of Egypt was found, the array of riches astonished the world. “Another great civilization that used crystals in their everyday life was Atlantis. They used crystals for everything, technology, such as their flying vehicles, Vimana’s used crystal technology to fly, and communications equipment used crystals as well. Crystals were also used for healing, for recording information and telepathic communications. It was said that the wise ones of Atlantis programmed various types of crystals with information and sacred knowledge that would help future generations. When the time was right, those crystals would appear on earth to help humanity evolve. According to Edgar Cayce, who is known as the Sleeping Prophet and an authority on Atlantis lore the Atlanteans had unique technologies that used powerful crystals as the source of their power. These crystals were huge and possessed great strength of these unique technologies. They were known as “Fire-Crystals”. It has been said that the misuse of these “Fire-Crystals” was the reason for the sinking and destruction of Atlantis. The power of “Fire-Crystals” were akin to the nuclear power of today. It is said that these crystals still remain under water in the Bermuda Triangle. These Fire-Crystals still emit some sort of energy fields that disrupt passing by aircrafts, ships etc. 
The Greeks, Tibetans, Romans believed crystals influenced and affected the physical body, thus wore amulets and talisman’s made of crystal and gemstones. This aided the wearer in healing, to ward off psychic attacks and to gain wisdom. Some would recite mantras or words of power to enhance the power of gemstones and crystals. It has been said that ancient Buddhists and Tibetans used crystals bowls for healing and producing light, for protection, and also in their sacred mandala’s. The Chinese were said to use crystals for healing meditation. The Mayans were said to use crystals as vision stones. They would layout the crystals in an elaborate formation on ley lines, the earth’s energy veins.
Significantly, the Incan Temple of the sun, and the pyramid complexes of the Maya’s were all located on earth energy lines. There is thus reason to believe that the ancients possessed the ability of transmitting images along these lines, and crystal lenses or screens were used at specific centers to transform the images into pictures, much like a modern television set.
