" The Earthkeepers believe that the world is real, but only because we've dreamed it into being. But dreaming requires an act of courage, for when we lack it, we have to settle for the world that's being created by our culture or by our genes - we feel we have to settle for the nightmare. To dream courageously, we must be willing to use our hearts. "
