老子 Lao Tze

道可道，非常道。名可名，非常名。無名天地之始。有名萬物之母。故常無欲以觀其妙。常有欲以觀其徼。此兩者同出而異名，同謂之玄。玄之又玄，眾妙之門。

There is no absolute reasoning behind everything, just like there is
no general name for every object.

The world was created without a name, and we started ours by naming
them one by one.

Restrain ourselves, we sense the subtleness of the world.
Releas ourselves, we sense the boundary of the world.

These two have the same origin, but with different names.

Because of this same origin, we appreciate the profound theory behind it.
This is so profound; we think it』s the gate that leads to all other secrets in the world.
