In some versions of Navajo healing traditions, a star gazer completes a ceremony to diagnose the type of illness a patient has. The star gazer first creates a sandpainting in his patient's hogan. He then exits the hogan to sing star-songs and use a “glass rock” to cast light upon the hogan or the patient. The color of light that comes from the quartz crystal determines if it is a serious sickness or not. The star-gazer uses this information to give a diagnosis on the illness.
