There is a thing inherent and natural which existed before heaven and earth. Motionless and fathomless, It stands alone and never changes; It pervades everywhere and never becomes exhausted. It may be regarded as the Mother of the Universe. I do not know its name. If I am forced to give It a name, I call it Tao, and I name it as supreme.
Thus it is that "Some things are increased by being diminished, others are diminished by being increased." What others have taught, I also teach; verily, I will make it the root of my teaching.
Nothing in the world is as soft and yielding as water. Yet for dissolving the hard and inflexible, nothing can surpass it. The soft overcomes the hard; the gentle overcomes the rigid. Everyone knows this is true, but few can put it into practice. Therefore the Master remains serene in the midst of sorrow. Evil cannot enter his heart. Because he has given up helping, he is people's greatest help. True words seem paradoxical.
Seal the openings, shut the doors, and until your last day you will not be exhausted. Widen the openings, interfere, and until your last day you will not be safe.
