Tao Te Ching Chapter 47
translated by Ursula K. Le Guin

You don't have to go out the door
to know what goes on in the world.
You don't have to look out the window
to see the way of Heaven.
The farther you go
the less you know.

So the wise soul
doesn't go, but knows;
doesn't look, but sees;
doesn't do, but gets it done.
