《庄子·外篇·山木》
鲁侯说： 我学习先王治国的办法，承继先君的事业；我敬仰鬼神尊重贤能，身体力行，没有短暂的止息，可是仍不能免除祸患，我因为这个缘故而忧虑。 
鲁侯曰： 吾学先王之道，修先君之业；吾敬鬼尊贤，亲而行之，无须臾离居。然不免于患，吾是以忧。 
Duke Lu said: I learn the methods of the former kings to rule the country and inherit the cause of my ancestors; I revere ghosts and deities, respect the wise and capable, exert myself in action, and never briefly pause, yet I still cannot escape disasters. I am troubled because of this.
