Tao Te Ching by Lao-Tze — Read

Sincere words are not fine; fine words are not sincere. Those who are skilled (in the Dao) do not dispute (about it); the disputatious are not skilled in it. Those who know (the Dao) are not extensively learned; the extensively learned do not know it.

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.
