That which is incomplete will be made complete, that which is crooked will straighten, that which is empty will be filled, that which is worn out will be renewed.
He who has little can only gain, but gain too much and the way will be lost.
Therefore the wise person holds to the Tao, and he is the example for all people.
Because he does not show himself, he shines brightly. Because he is not righteous, he is distinguished. Because he does not boast, he is successful. Because he is not proud, he endures. Because he is not contentious, no one contends with him.
The ancients said: That which can bend will remain whole. Is this not true? To be humble is to remain in the Tao.
(from Tao Te Ching, verse 22, translation by Robert Brookes)
