Ayurveda is the ancient system of healing from India. It's got a holistic approach to healing, trying to integrate among other things excersise, meditation, crystal healing and more. In these old texts it is said that the light of the Creator is transmitted to Earth by the planets; and gemstones collect and radiate this energy.
