Marcus Aurelius Quote
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.
Variant translation: Nowhere can man find a quieter or more untroubled retreat than in his own soul. - Meditations (c. 161–180 CE) - Book IV
