Chapter 31, Part M - Chuang Tzu

Yen Yuan brought the carriage around, Tzu-lu held out the strap for pulling oneself up, but Confucius, without turning in their direction, waited until the ripples on the water were stilled and he could no longer hear the sound of the pole before he ventured to mount.

Tzu-lu, following by the side of the carriage, said, "I have been permitted to serve you for a long time, Master, but I have never seen you encounter anyone who filled you with such awe. The rulers of ten thousand chariots, the lords of a thousand chariots, when they receive you, invariably seat you on the same level as themselves and treat you with the etiquette due to an equal, and still you maintain a stiff and haughty air.

"But now this old fisherman, pole in hand, presents himself in front of you, and you double up at the waist, as bent as a chiming-stone, and bow every time you reply to his words - this is going too far, isn't it? Your disciples all are wondering about it. Why should a fisherman deserve such treatment?"
