Tao Te Ching · Ch. 12

五色令人目盲;五音令人耳聾;五味令人口爽;馳騁畋獵,令人心發狂;難得之貨,令人行妨。是以聖人為腹不為目,故去彼取此。

Wǔ sè lìng rén mù máng; Wǔ yīn lìng rén ěr lóng; Wǔ wèi lìng rén kǒu shuǎng; Chí chěng tián liè, lìng rén xīn fā kuáng; Nán dé zhī huò, lìng rén xíng fáng. Shì yǐ shèng rén wéi fù bù wéi mù, gù qù bǐ qǔ cǐ.

The five colors blind the eye; the five tones deafen the ear; the five flavors dull the palate. Racing and hunting drive the mind wild; rare and precious goods obstruct one's conduct. Therefore the sage attends to the belly and not the eye — he sets aside that and takes up this.
