"To protect yourself from lightning, the Navajo say, wear a bead of turquoise in your hair. The Navajo divinity Changing Woman, so named because she is life springing from nothing and a woman who renews her youth each season, lives in a house with a turquoise door and four footprints of turquoise leading to a turquoise room. Changing Woman looks through binoculars of rock crystal, the stone of light beams and fire and a natural ally of turquoise. Carried on the tongue, rock crystal is the word in a prayer that means truth."
