《礼记·哀公问》
由自身要推想到百姓，由自己的儿子要推想到百姓的儿子，由自己的妻子要推想到百姓的妻子。君子如能实行这三点，礼就会遍行于天下，过去周太王就是这样做的。能这样做，国家就安定了。 
身以及身，子以及子，妃以及妃，君行此三者，则忾乎天下矣，大王之道也。如此，国家顺矣。 
Start with yourself to understand the common people. Start with your own sons to understand the sons of the common people. Start with your own wife to understand the wives of the common people. If a gentleman could implement these three points, propriety would spread far and wide throughout the world. This was exactly what King Tai of Zhou in the past did. If you can do this, the country will be stable.
