It is not natural to stand on tiptoe, or being astride one does not walk. One who displays himself is not bright, or one who asserts himself cannot shine. A self-approving man has no merit, nor does one who praises himself grow.
The relation of these things (self-display, self-assertion, self-approval) to Tao is the same as offal is to food. They are excrescences from the system; they are detestable; Tao does not dwell in them.
