Though Confucius served the Duke of Lu, a Chinese state, he made many enemies with the nobles of the land. His views antagonized the powerful nobles, who wanted the Duke to be a puppet in their hands. Confucius was exiled from the State of Lu for more than two decades. He lived in the countryside, spreading his teachings.

Forget injuries, never forget kindnesses.

When things are investigated, then true knowledge is achieved; when true knowledge is achieved, then the will becomes sincere; when the will is sincere, then the heart is set right ; when the heart is set right, then the personal life is cultivated; when the personal life is cultivated, then the family life is regulated; when the family life is regulated, then the national life is orderly; and when the national life is orderly, then there is peace in this world.

Without Goodness one cannot enjoy enduring happiness

If language is not correct, then what is said is not what is meant; if what is said is not what is meant, then what must be done remains undone; if this remains undone, morals and art will deteriorate; if justice goes astray, the people will stand about in helpless confusion. Hence there must be no arbitrariness in what is said. This matters above everything.

The superior man makes the difficulty to be overcome his first interest; success only comes later.

Reviewing what you have learned and learning anew, you are fit to be a teacher.
