父在，觀其志；父殁，觀其行；三年无改於父之道，可謂孝矣。 - Confucius

To be wronged is nothing, unless you continue to remember it.

The institutions of the Ruler are rooted in his own character and conduct, and sufficient attestation of them is given by the masses of the people. He examines them by comparison with those of the three kings, and finds them without mistake. He sets them up before Heaven and Earth, and finds nothing in them contrary to their mode of operation. He presents himself with them before spiritual beings, and no doubts about them arise. He is prepared to wait for the rise of a sage a hundred ages after, and has no misgivings. His presenting himself with his institutions before spiritual beings, without any doubts arising about them, shows that he knows Heaven. His being prepared, without any misgivings, to wait for the rise of a sage a hundred ages after, shows that he knows men.

In all things success depends on previous preparation, and without such previous preparation there is sure to be failure. If what is to be spoken be previously determined, there will be no stumbling. If affairs be previously determined, there will be no difficulty with them. If one's actions have been previously determined, there will be no sorrow in connection with them. If principles of conduct have been previously determined, the practice of them will be inexhaustible.
