修观
原文
善建不拔，善抱者不脱，子孙以祭祀不辍。修之于身，其德乃真；修之于家，其德乃馀；修之于乡，其德乃长；修之于国，其德乃丰；修之于天下，其德乃普。故以身观身，以家观家，以乡观乡，以国观国，以天下观天下。吾何以知天下然哉？以此。
王弼注
善建者不拔，固其根而后营其末，故不拔也。善抱者不脱，不贪于多，齐其所能，故不脱也。子孙以祭祀不辍。子孙传此道以祭祀则不辍也。修之于身，其德乃真；修之于家，其德乃馀；以身及人也，修之身则真，修之家则有馀，修之不废，所施转大。修之于乡，其德乃长；修之于国，其德乃丰；修之于天下，其德乃普。故以身观身，以家观家，以乡观乡，以国观国，彼皆然也。以天下观天下。以天下百姓心观天下之道也，天下之道，逆顺吉凶，亦皆如人之道也。吾何以知天下然哉？以此。此上之所云也。言吾何以得知天下乎，察己以知之，不求于外也，所谓不出户以知天下者也。

(The cultivation (of the Dao), and the observation (of its effects)) What (Dao's) skilful planter plants Can never be uptorn; What his skilful arms enfold, From him can never be borne. Sons shall bring in lengthening line, Sacrifices to his shrine. Dao when nursed within one's self, His vigour will make true; And where the family it rules What riches will accrue! The neighbourhood where it prevails In thriving will abound; And when 'tis seen throughout the state, Good fortune will be found. Employ it the kingdom o'er, And men thrive all around. In this way the effect will be seen in the person, by the observation of different cases; in the family; in the neighbourhood; in the state; and in the kingdom. How do I know that this effect is sure to hold thus all under the sky? By this (method of observation).
