《淮南子·诠言训》
身心处于恬愉舒适之中，身体处于安逸闲适之中，等待天命的安排，内心自寻快乐，不着急身外的琐事，虽天下之大也不足以变易他的生活模式，日月隐藏也不能干扰他的生活态度。所以虽然低贱但他觉得尊贵，虽然贫寒他觉得富足。
游心于恬，舍形于佚，以俟天命，自乐于内，无急于外，虽天下之大，不足以易其一概日月廋而无溉于志，故虽贱如贵，虽贫如富。
When both the body and mind are calm and comfortable, and the body is at ease and at leisure, just wait for the order of Heaven’s time and find joy internally. Do not rush into external trifles. Even if the world is large, it cannot change his living habits, and even if sun and moon hide, it cannot affect his life attitude. Thus, though he is humble, he feels himself to be honorable; though he is poor, he finds himself to be rich.
