Heavy is the root of light.
Those who are unswerving have resolve
Without 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.
Face the simple fact before it comes involved. Solve the small problem before it becomes big.
A good runner leaves no footprints.
The longer you travel, the less you know.
