When the world is ruled according to the Way, the ghosts lose their power. The ghosts do not really lose their power, but it is not used to harm people.
When the Way is lost there is virtue. When virtue is lost there is benevolence. When benevolence is lost there is righteousness. When righteousness is lost there are rituals.
Heaven and Earth last for ever. Why do Heaven and Earth last for ever? They are unborn, so ever living. The sage stays behind, thus he is ahead. He is detached, thus at one with all. Through selfless action, he attains fulfillment.
