Every human being's essential nature is perfect and faultless, but after years of immersion in the world we easily forget our roots and take on a counterfeit nature.
Without stirring abroad, One can know the whole world; Without looking out of the window One can see the way of heaven. The further one goes The less one knows.
The whole world says that my Way is great like nothing else. It is great because it is like nothing else. If it were like everything else, it would long ago have become insignificant.
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.
