" A myth, therefore, is true because it is effective, not because it gives us factual information. If, however, it does not give us new insight into the deeper meaning of life, it has failed. If it works, that is, if it forces us to change our minds and hearts, gives us new hope, and compels us to live more fully, it is a valid myth. Mythology will only transform us if we follow its directives. A myth is essentially a guide; it tells us what we must do in order to live more richly. If we do not apply it to our own situation and make the myth a reality in our own lives, it will remain as incomprehensible and remote as the rules of a board game, which often seem confusing and boring until we start to play. "
