„When the passions, such as joy, anger, grief, and pleasure, have not awakened, that is our central self, or moral being (chung). When these passions awaken and each and all attain due measure and degree, that is harmony, or the moral order (ho). Our central self or moral being is the great basis of existence, and harmony or moral order is the universal law in the world.
When our true central self and harmony are realised, the universe then becomes a cosmos and all things attain their full growth and development.“
— Zisi Chinese philosopher -481 - -402 v.Chr
Variant translation: "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 harmony is the illustrious Way. When a man has achieved the inner self and harmony, the heaven and earth are orderly and the myriad things are nourished and grow thereby."
As translated by Lin Yutang in The Importance of Living (1937), pp. 143–144
