Sometimes one is strong, and sometimes weak, sometimes healthy, and sometimes in poor health; sometimes is first, and at other times behind. The wise follower of The Way does not try to change the world by force, for he knows that force results in like force. He avoids extremes and excesses, yet does not become complacent. The external world is fragile, and he who meddles with its natural way, risks causing damage to himself, for he is not apart nor above consequence.
