人们四处寻求退隐之地，到乡间、海滨和山中去；你也常常渴望这样的去处。然而这不过是凡俗之人的想法，因为只要你愿意，你随时都可以退回到自己内心之中。一个人退隐到自己的心灵里，比退隐到任何地方都更宁静、更少烦扰，尤其是当他心中存有那样的思想，一旦向内审视，便能立刻获得完全的安宁。

——马可·奥勒留

Men seek retreats for themselves, houses in the country, sea-shores, and mountains; and thou too art wont to desire such things very much. But this is altogether a mark of the most common sort of men, for it is in thy power whenever thou shalt choose to retire into thyself. For nowhere, either with more quiet or more freedom from trouble, does a man retire than into his own soul, particularly when he has within him such thoughts that by looking into them he is immediately in perfect tranquility.

—Marcus Aurelius
