Tao Te Ching 22

The partial becomes complete; the crooked, straight; the empty, full; the worn out, new. He whose desires are few gets them; he whose desires are many goes astray.

Therefore the sage holds in his embrace the one thing of humility, and manifests it to all the world. He is free from self-display, and therefore he shines; from self-assertion, and therefore he is distinguished; from self-boasting, and therefore his merit is acknowledged; from self-complacency, and therefore he acquires superiority. It is because he is thus free from striving that therefore no one in the world is able to strive with him.

That saying of the ancients that 'the partial becomes complete' was not vainly spoken:- all real completion is comprehended under it.
