The spirit of the Tao's contract

When a deep resentment is patched up, some resentment is sure to remain. How can repaying resentment with kindness be considered truly good? So the sage holds the left half of a debt contract, but does not demand payment from others. A person of virtue is like one who keeps the contract—easy and forgiving. A person without virtue is like a tax collector—harsh and exacting. The Tao of Heaven has no favorites. It always stands with good people.
