Of all natural objects, crystals most clearly demonstrate how all forms, including the human body, manifest a characteristic vibrational pattern. The form of each different type of crystal is determined by the particular geometric pattern of its molecular structure. This geometric pattern, which shaped the crystal, continues to vibrate- as does every other molecule. But the qualities of certain crystals' vibrations, such as quartz, make them an effective tool for many body and/or energy practitioners due to their power to focus and/or amplify the energy being directed by the practitioner into the patient's biofield. Crystals may also be worn on the body or placed in one's living space
