Chapter 4, Part 15 - Confucius

The Master said, "Shan, my doctrine is that of an all-pervading unity." The disciple Tsang replied, "Yes."

The Master went out, and the other disciples asked, saying, "What do his words mean?"

Tsang said, "The doctrine of our master is to be true to the principles of our nature and the benevolent exercise of them to others, this and nothing more."
