Tao Te Ching: Chapter 3

No favourites, no rivalry.

No treasures, no thievery.

No objects of passion, no loss of contentment.

So keep the mind empty and keep the heart full.

Weaken ambition and strengthen the bones.

Know nothing, want nothing, do nothing,

and things will look after themselves.

We practice our art to follow the way that moves in accordance with natural law, and that is art for heart's sake.
