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.
Knowing constancy, the mind is open.
With an open mind, you will be openhearted.
Being openhearted you will act royally.
Being royal, you will attain the divine.
Being divine, you will be at one with the Tao.
Being at one with the Tao is eternal.
Though the body dies, the Tao will never pass away.
