All things issue from it; all things return to it. To find the origin, trace back the manifestations. When you recognize the children and find the mother, you will be free of sorrow. If you close your mind in judgements and traffic with desires, your heart will be troubled. If you keep your mind from judging and aren't led by the senses, your heart will find peace. Seeing into darkness is clarity. Knowing how to yield is strength. Use your own light and return to the source of light. This is called practicing eternity.
In this world, there is nothing softer or thinner than water. But to compel the hard and unyielding, it has no equal. That the weak overcomes the strong, that the hard gives way to the gentle - this everyone knows. Yet no one asks accordingly.
The reason why rivers and seas are able to be lords over a hundred mountain streams, is that they know how to keep below them. That is why they are able to reign over all the mountain streams.
In the highest antiquity, the people did not know that there were rulers. In the next age they loved them and praised them. In the next they feared them; in the next they despised them.
So sometimes things are ahead and sometimes they are behind; Sometimes breathing is hard, sometimes it comes easily; Sometimes there is strength and sometimes weakness; Sometimes one is up and sometimes down. Therefore the sage avoids extremes, excesses, and complacency.
The Tao is the center of the universe, the good man's treasure, the bad man's refuge. Honors can be bought with fine words, respect can be won with good deeds; but the Tao is beyond all value, and no one can achieve it. Thus, when a new leader is chosen, don't offer to help him with your wealth or your expertise. Offer instead to teach him about the Tao. Why did the ancient Masters esteem the Tao? Because, being one with the Tao, when you seek, you find; and when you make a mistake, you are forgiven. That is why everybody loves it.
