《黄帝四经·经法·六分》
天下安定宁和在于君主执度公正以明其德，同时效法天地公平无私，这样就可以称王天下。
天下太平，正以明德，参之于天地，而兼覆载而无私也，故王天下。
The world is peaceful and tranquil when the monarch adheres to just standards to make his virtue clear and at the same time emulates Heaven and Earth's fairness and selflessness. This way, he can become king over all under Heaven.
