《老子》 第二章　

　　天下皆知美之为美，斯恶矣；皆知善之为善，斯不善矣。
　　故有无相生，难易相成，长短相形，高下相倾，音声相和，前后相随……
　　 是以圣人处无为之事，行不言之教，万物作焉而不辞，生而不有，为而不恃，功成而不居。
　　夫唯不居，是以不去。

天下人都知道什么是美，同样地都知道什么是丑；天下人都知道什么是善，同样地都知道什么是不善。

所以，根据有与无两个方面,可以测量认识生的相。根据难与易两个方面可以测量认识成的相。根据长与短两个方面可以测量认识形的相。根据高与下两个方面可以测量认识倾的相。根据音与声两个方面可以测量认识和谐的相。根据前胸与后背两个方面可以测量认识随的相。因此圣人不做不说。万物运作但不推辞，作为但不凭恃，成功但不停留。因为不停留，所以也就不介意离开。

Everyone knows what beauty is and what is ugly; everyone knows what is good and what is bad.

Therefore, according to Something and Nothing two aspects, can cognition the Born phase; according to difficulty and ease two aspects, can cognition the Formed phase;Shape phase can be measured according to the two aspects of length and short. Tilted phase can be measured according to the two aspects of high and lower。According to the two aspects of voice and sound, we can measure A harmonious phase.  Accompanying phase can be measured according to the front chest and back.

 Therefore the saint does nothing and say no word. Act but not rely on, success but not stay. Because do not stay, so do not mind leaving.

《老子》第一章
　　道可道，非常道；名可名，非常名。
　　无，名天地之始；有，名万物之母。
　　故常无，欲以观其妙；常有，欲以观其徼。
　　此两者同出而异名，同谓之玄。
　　玄之又玄，众妙之门。

道满足道，但不是常态的道。名满足名，但不是常态的名。无是天地的开始的名，有是万物的母亲的名。所以，定义了无就能发现天地的美，定义了有就能观察万物的边界。常态的有与常态的无两者共同从玄这个地方出来，但它们的名不同。从一个玄走向另一个玄，是发现众多美妙的门户。

The Way satisfies the Way, but it is not the normal Way. The name satisfies the name, but not the name of the normal. Nothing is the name of the beginning of the world,Something is the name of the mother of everything. Therefore, the definition of nothing can discover the beauty of the world . Something  defines the boundary of being to observe everything. Normal Something  and normal Nothing come from this place of black hole together, but their names are different. Moving from one black hole to another is the  gateways to discovery of many beauty .

《老子》第十六章　　　　　　　　　　　　　　　　　
     致虚极，守静笃，万物并作，吾以观其复。
     夫物芸芸，各复归其根。
     归根曰静，是曰复命。
     复命曰常，知常曰明。
     不知常，妄作，凶。
     知常，容。
     容乃公，公乃王，王乃天，天乃道，道乃久，没身不殆。

【译文】
    尽可能地使自己的心灵空虚，尽可能地使自己的身体保持安静，在万物的事态演变中，我们来观察它们的循环反复。事事物物虽然纷纭繁杂，但它们都归结于它们的根本。归结到根本它们就显示出安静，这就叫做重复周期。
    万物有根的归根向静的周期性重复运动叫做常，知晓了解这个常叫做明，如同黑暗中点起了火把。不知常如同人在黑暗中，如果盲目作为就会充满凶险。知常，进一步就看到了万事万物的样子，叫做容。认识了万物的容，就能认识万物的共同特性，叫做公。公以后更进一步就可以做万物的主人，叫做王。王进一步就可以认识到天。天再进步就是道，道可以永久存在，我的身体消失了万物之道的运动也不会停止。

Make your mind empty as much as possible, keep your body as quiet as possible, and in the course of events we observe their cycles. Things are complicated. But they all come down to their root. When they come down to the root, they show quiet, which is called the repeated cycle. The root of everything in the periodic motion to the static is called Chang, knowing that understanding this is often called the Ming. Like a torch lit in the dark. I do not know often like a man in the dark, if blind action will be filled with danger. Know the constant, further see the appearance of all things, called Rong. Knowing the face of all things, we can understand the face of all things The common characteristic of all things is called the public. After the public can be the master of all things, called the king. The king can further realize that heaven. Heaven progress is the Way, Way can exist forever. The movement of my body that has disappeared from the path of all things will not stop.
