Tao Te Ching

“From the birth of mankind until now, there has never been the equal of Confucius… I have all my life had the sky over my head, but I do not know its height, and the earth under my feet, but I do not know its thickness. In my serving of Confucius, I am like a thirsty man who goes with his pitcher to the river, and there he drinks his fill, without knowing the river's depth.”

— Duanmu Ci 端木赐 520 – 456 BCE
(Tzu Kung, Zigong)
