视之不见，名曰夷；听之不闻，名曰希； 搏之不得，名曰微。此三者不可致诘，故混而为一。其上不皦，其下不昧。绳绳兮不可名，复归于无物。是谓无状之状，无物之象，是谓惚恍。迎之不见其首，随之不见其后。执古之道，以御今之有。能知古始，是谓道纪。

TheInvisble Energy of Tao

Look,and it can not be seeen.

Listen,and it can not be heard.

Reach,and it can not be grasped.

Thesethree cannot be separated,

sothey mingle and act as one.

Above,it isn’t bright.

Below,it isn’t dark.

Endlessly,the nameless  goes on,

Mergingand returning to nothingness.

We call it theformless Form, the imageless Image.

We call it theindefinable and unimaginable.

Confront it and thereis no beginning .

Follow it and thereis no end.

By adhering to the Tao of the past You will master theexistence of the present And be able to know the origin of the past. This iscalled the clue of Tao.

 [译文]

道之存在是人类肉眼看不见、 耳朵听不到、 肢体触摸不着的。这三件事不能进一步分解，浑然构成一体宇宙场。它的上面显得光明亮堂，下面不显得阴暗。它不可名状却绵绵不绝，又回归于无边无际，无物的道本源意识能。因此可称为恍然无形、不见物体的形象，恍恍惚惚。迎着不见其头，跟随不见其尾。
