A crystal or crystalline solid is a solid material whose constituent atoms, molecules, or ions are arranged in an orderly repeating pattern extending in all three spatial dimensions. They have many remarkable properties: crystals of a species always have the same inclination angle between their surfaces. Their colors are determined by tiny impurities. Rock crystal and Tumalin also show the piezoelectric effect – which means that they convert pressure energy into electrical energy. If you rub quartz crystals in the dark, they begin to glow from within. Other crystals such as hematite can be magnetised for a long time. Crystals can absorb, reflect and transform energy.

Energy healers use crystals to direct and amplify prana-energy – or to program them with certain qualities. Especially quartz crystals are suitable as energy suppliers and holders.  Beware of overloading with crystal energy – if you’ve got too much, take a shower.
