Melody and harmony are like lines and colors in pictures. A simple linear picture may be completely beautiful; the introduction of color may make it vague and insignificant. Yet color may, by combination with lines, create great pictures, so long as it does not smother and destroy their value.
Rabindranath TagoreThis principle of opposites is at the very root of Creation, which is divided between the rule of the King and the Queen; Night and Day; the One and the Varied; the Eternal and the Evolving.
Rabindranath Tagore
