Lao-Tzu said 'the five colors make a man blind, the five tones make
a man deaf.' .[If] you can only see five colors, you're blind,
and if you can only hear five tones in music, you're deaf. 
[If] you force sound into five tones, you force color into five
colors, you're blind and deaf. The world of color is infinite, as is
the world of sound. And it is only by stopping fixing conceptions on
the world of color and the world of sound that you really begin to
hear it and see it.
