Bi Xi called for Confucius, and Confucius was tempted to go.
Zilu said, “I remember you saying, ‘A noble person won’t associate with someone who is committing evil.’ Now Bi Xi is about to use his stronghold in Zhong Mou to start a rebellion. How can you even consider joining him?”
Confucius replied, “Yes, I did say that. But what resists grinding is truly strong and what resists black dye is truly white. Should I be like a bitter gourd, hanging on a string as decoration but not fit to eat?”
