道德經  Tao Te Ching :  XIV

 

道其上不皦 、其下不昧 。

繩繩不可名 、復歸於無物 。

是謂無狀之狀 、無物之象 、是謂惚恍 。

迎之不見其首 、隨之不見其後 。

 

Its upper part is not dazzling;

Its lower part is not obscure.

 

Dimly visible, it cannot be named;

And returns to that which is without substance.

 

This is called the shape that has no shape;

The image that is without substance;

This is called indistinct and shadowy.

 

Go up to it and you will not see its head;

Follow behind it and you will not see its rear.
