What is God-given is called nature; to follow nature is called Tao (the Way); to cultivate the way is called culture. Before joy, anger, sadness and happiness are expressed, they are called the inner self; when they are expressed to the proper degree, they are called harmony. The inner self is the correct foundation of the world, and the harmony is the illustrious Way. When a man has achieved the inner self and harmony, the heaven and earth are orderly and the myriad of things are nourished and grow thereby.
ConfuciusIn the Book of Poetry there are three hundred poems, but the meaning of all of them may be put in a single sentence: Have no debasing thoughts.
ConfuciusThings being investigated, knowledge became complete. Their knowledge being complete, their thoughts were sincere. Their thoughts being sincere, their hearts were then rectified. Their hearts being rectified, their persons were cultivated. Their persons being cultivated, their families were regulated. Their families being regulated, their States were rightly governed. Their States being rightly governed, the whole kingdom was made tranquil and happy.
