不出户，知天下；不窥牖，见天道。
1Without going outside his door, one understands (all that takes place) under the sky; without looking out from his window, one sees the Tao of Heaven.
其出弥远，其知弥少。
2The farther that one goes out (from himself), the less he knows.
是以圣人不行而知，不见而明，不为而成。
3Therefore the sages got their knowledge without travelling; gave their (right) names to things without seeing them; and accomplished their ends without any purpose of doing so.
