Heaven and Earth last for ever. Why do Heaven and Earth last for ever? They are unborn, so ever living. The sage stays behind, thus he is ahead. He is detached, thus at one with all. Through selfless action, he attains fulfillment.
The valley spirit never dies; It is the woman, primal mother. Her gateway is the root of heaven and earth. It is like a veil barely seen. Use it; it will never fail.
Heaven and earth are ruthless; They see the ten thousand things as dummies. The wise are ruthless; They see the people as dummies. The space between heaven and earth is like a bellows. The shape changes but not the form; The more it moves, the more it yields. More words count less. Hold fast to the center.
