" And you know the darkness beyond despair, just as intimately as you know the soaring heights. Because in this and all universes, there is balance. You can't have the one without facing the other. And sometimes you think you can take it because the joy is worth the despair, and sometimes you know you can't take it and how did you ever think you could? And there is the dance; strength and weakness, confidence and desolation. "
