Meditation 3.16
16. Body, vital spirit, mind: of the body, sense perceptions; of the vital spirit, impulses; of the mind, doctrines. To be impressed by images belongs also to the beasts of the field, to be swayed by the strings of impulse to wild beasts, to men who sin against nature, to a Phalaris or a Nero. To have the mind as guide to what appear to be duties belongs also to men who do not believe in gods, who betray their own country, who do anything and everything once they have locked their doors. If then all else is common to you with those whom I have mentioned, it remains the peculiar mark of the good man to love and welcome what befalls him and is the thread fate spins for him; not to soil the divinity seated within his breast nor to disquiet it with a mob of imaginations, but to preserve and to propitiate it, following God in orderly wise, uttering no word contrary to truth, doing no act contrary to justice. And if all men disbelieve that he lives simply, modestly, and cheerfully, he is not angry with any one of them nor diverted from the road that leads to the goal of his life, at which he must arrive, pure, peaceful, ready to depart, in effortless accord with his own birth-spirit.
