The transformation toward eternal life is gradual. The heavy gross energy of body, mind, and spirit must first be purified and uplifted. When the energy ascends... then self mastery can be sought.
Man, when living, is soft and tender; when dead, he is hard and tough. All animals and plants when living are tender and delicate; when dead they become withered and dry. Therefore it is said: the hard and tough are parts of death; the soft and tender are parts of life.
Therefore, if a great kingdom humbles itself before a small kingdom, it shall make that small kingdom its prize. And if a small kingdom humbles itself before a great kingdom, it shall win over that great kingdom. Thus the one humbles itself in order to attain, the other attains because it is humble. If the great kingdom has no further desire than to bring men together and to nourish them, the small kingdom will have no further desire than to enter the service of the other. But in order that both may have their desire, the great one must learn humility.
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.
Other people are joyous, like on the feast of the ox, like on the way up to the terrace in the spring. I alone am inert, giving no sign, like a newborn baby who has not learned to smile.
As it acts in the world, the Tao is like the bending of a bow. The top is bent downward; the bottom is bent up. It adjusts excess and deficiency so that there is perfect balance.
The good man is the teacher of the bad, And the bad is the material from which the good may learn. He who does not value the teacher, Or greatly care for the material, Is greatly deluded although he may be learned. Such is the essential mystery.
