Without going out of your door
You can know all things of earth
With out looking out of your window
You could know the ways of heaven
The farther one travels
The less one knows
The less one really knows
Arrive without traveling
See all without looking
Do all without doing
I never really understood this song until I moved half way around the world.
And then, of course, learning to practice has slowly let me see not knowing on a more subtle level...
