"At the heart of American Indian oral tradition is a deep and unconditional belief in the efficacy of language. Words are intrinsically powerful. They are magical. By means of words one can bring about physical change in the universe... one can quiet the raging weather, bring forth the harvest, ward off evil, rid the body of sickness and pain, subdue an enemy, capture the heart of a lover, live in the proper way, and venture beyond death. ...there is nothing more powerful. ...To be careless in the presence of words... is to violate a fundamental morality."
