Tao – Chapter 12

The five colors cause one's eyes to go blind.
Racing horses and hunting cause one's mind to go mad.
Goods that are hard to obtain pose an obstacle to one's travels.
The five flavors confuse one's palate.
The five tones cause one's ears to go deaf.

Therefore, in the government of the Sage:
He's for the belly and not for the eyes.
Thus he rejects that and takes this.
