"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."
