The river and sea can be kings of the hundred valley streams because they are good at lying below them. For this reason, They can be kings of the hundred valley streams. For this reason, too, If the sage wants to be above the people, in his words, he must put himself below them; If he wishes to be before the people, in his person, he must stand behind them. Therefore, He is situated in front of the people, but they are not offended; He is situated above the people, but they do not consider him a burden. All under heaven happily push him forward without wearying. Is this not because he is without contention? Therefore, No one under heaven can contend with him.
