Without 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. The farther that one goes out (from himself), the less he knows.
不出戶，知天下；不窺牖，見天道。其出彌遠，其知彌少。是以聖人不行而知，不見而明，不為而成。
Therefore 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.
