Zeng Zi saw Zi Xia and asked him, "Why have you gained weight?"
Zi Xia replied, "I have won a victory, and that is why I have gained weight."
"What victory do you refer to?" Zeng Zi inquired.
Zi Xia explained, "When I immersed myself in reading, I revered the principles of the ancient emperors and sages. When I went out, I admired the pleasures of a wealthy life. A battle raged between these two desires in my mind, and they were evenly matched. This inner conflict left me emaciated. Now, the principles of the ancient sages have prevailed. My mind has grown increasingly peaceful, and so I have gained weight."
