Crystal healing is the belief that certain crystal (also known as charmstones) have metaphysical energies in them which can be used to heal the body and soul. While this idea is not accepted by most modern scientists, the art of using crystals for healing and other purposes has been practiced throughout history. Native American and Australian Aboriginal, the Shalagram and Lingam traditions in Hinduism, and others have used these stones. In modern times they have been popular with the New Age movement.
One theory behind crystal healing is that certain crystals vibrate energy at a particular rate, which, when put near the body, change the bodies aura and vibrational rate to correspond with that of the crystal. Crystals can be worn around the neck, or held next to the skin, or just carried on the person. A more advanced approach is to place stones or crystals along energy meridians and chakras.
