Things flourish, then each returns to its root. Returning to the root is called stillness: Stillness is called return to life, return to life is called the constant; knowing the constant is called enlightenment.
LaoziWithout going outside, you may know the whole world, without looking through the window, you may see the ways of heaven. The farther you go, the less you know. Thus the sage knows without traveling; he sees without looking; he works without doing.
Laozi
