The knower is not confused, the benevolent is not worried, and the brave is not afraid. ——& lt； Zi Han > The Analects of Confucius; What's the revelation?

Confucius said, "The wise are not chaotic, the wise are not sad, and the brave are not afraid."

Confucius clearly pointed out: the highest accomplishment of wisdom is not to be confused; The highest accomplishment of benevolence is not worrying; The highest achievement of courage is not being afraid. Although the requirement of sanctification is extremely high and difficult to achieve, it can still be achieved through practice. Because, if a person really understands the real purpose of being a man, he will improve his mind because of his self-requirement, break the mystery of life, and then face the fun of life calmly without disturbing others, and also exercise his fearless real courage to face the difficulties and tests he encounters. Confucius hopes that his students can have these three virtues and become real gentlemen. Nan huaijin also interpreted this sentence of Confucius. He means that this sentence of Confucius contains three meanings, that is, knowledge and cultivation meet the standards and must meet three conditions.
