Tao Te Ching Chapter 12
The five colors blind the eyes of man;
The five musical notes deafen the ears of man;
The five flavors dull the taste of man;
Horse-racing, hunting and chasing madden the minds of man;
Rare, valuable goods keep their owners awake at night.
Therefore the Sage:
Provides for the belly and not the eye.
Hence, he rejects the one and accepts the other.
