Without going out the door, know the world ;
Without peering out the window, see the Heavenly Tao.
The further one goes,
The less one knows.
Therefore the sage
Knows without going,
Names without seeing,
Achieves without striving.
I really loved it. It somehow connects to somewhere inside me, past the words, past touch. I have been trying to find out the original source for quite sometime but in vain.
