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.
LaoziThe supreme good is like water, which nourishes all things without trying to. It is content with the low places that people disdain. Thus it is like the Tao. In dwelling, live close to the ground. In thinking, keep to the simple. In conflict, be fair and generous. In governing, don't try to control. In work, do what you enjoy. In family life, be completely present. When you are content to be simply yourself and don't compare or compete, everybody will respect you.
Laozi
