以身观身，以家观家，以乡观乡，以邦观邦，以天下观天下。
《老子》第54章
Know a person in the perspective of a person，know a family in the perspective of a family ,know a neighborhood in the perspective of a neighborhood , know a state in the perspective of a state ,and know a kingdom in the perspective of a kingdom.
[注释]
以身观身:用修身的原则来观察个人。以，用。又蒋锡昌日:“‘以身观身’，言以修道之身，观不修道之身，孰得孰失，孰存孰亡也。下四句文谊，依此类推。”
[译文]
用修身的原则来观察个人，用齐家的原则观察全家，用理乡的原则观察全乡，用治国的原则观察全国，用平天下的原则观察天下。
