Since a three-dimensional object casts a two-dimensional shadow, we should be able to imagine the unknown four-dimensional object whose shadow we are.

Marcel Duchamp  (via sugarsickness)

Knowing others is intelligence; knowing yourself is true wisdom. Mastering others is strength; mastering yourself is true power. If you realize that you have enough, you are truly rich.

Lao Tzu, Tao Te Ching (via kushandwizdom)
