Lao Tse: The Tao Teh Ching Chapter 81
1. Sincere words are not fine; fine words are not sincere. Those
who are skilled (in the Tao) do not dispute (about it); the
disputatious are not skilled in it. Those who know (the Tao) are
not extensively learned; the extensively learned do not know
it.
2. The sage does not accumulate (for himself). The more that he
expends for others, the more does he possess of his own; the more
that he gives to others, the more does he have himself.
3. With all the sharpness of the Way of Heaven, it injures not;
with all the doing in the way of the sage he does not strive.
