《荀子·宥坐》
孔子说： 聪明睿智，就要用笨拙来保持它；功劳遍布天下，就要用谦让来保持它；勇敢盖世，就要用怯懦来保持它；富有天下，用谦虚来保持它。这就是所谓的保持盈满的方法啊。 
孔子曰： 聪明圣知，守之以愚；功被天下，守之以让；勇力抚世，守之以怯，富有四海，守之以谦：此所谓挹而损之之道也。 
Confucius said: To be intelligent and wise, one must maintain a dull appearance; with merits all over the world, one must maintain humility; with bravery that covers the world, one must maintain cowardice; with richness in the world, one must maintain modesty. This is the so-called way to stay full.
