The nine at the third line says: “The superior man works ten¬aciously all the day and keeps vigilant at night. There is danger but no harm. n What does it mean? Confucius says： “A superior man constantly cultivates his virtue and promotes his cause, loyalty and reliability can cultivate his virtue, and appropriate modi-fication of his words in sincerity is conducive to his cause. If a man knows his aims and strives to realize them, he is a man to be discussed with about the subtle signs of development of things. If he knows the appropriate time to end things and ends them time¬ly, then he is a man that can be cooperated with to keep things in their appropriate states of development. A man like this is not conceited in a high position and neither is he depressed in a hum¬ble position. Therefore, he keeps prudent and vigilant at any time and works tenaciously, even if he faces danger, he can be free from harm.
