Tao Te Ching Chapter 56

He who knows does not speak;

He who speaks does not know.

Fill up its apertures,

Close its doors,

Dull its edges,

Untie its tangles,

Soften its light,

Submerge its turmoil,

- This is the Mystic Unity.

 

Then love and hatred cannot touch him.

Profit and loss cannot reach him.

Honor and disgrace cannot affect him.

Therefore is he always the honored one of the world.
