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.
When you accurately perceive the fluidity of things, you can also begin to perceive the constancy behind them: the creative, transformative, boundless, immutable Tao.
As it acts in the world, the Tao is like the bending of a bow. The top is bent downward; the bottom is bent up. It adjusts excess and deficiency so that there is perfect balance.
