The Meditations and the Enchiridion

“Epictetus, Enchiridion 1: 'Some things are in our control and others not. Things in our control are opinion, pursuit, desire, aversion, and, in a word, whatever are our own actions. Things not in our control are body, property, reputation, command, and, in one word, whatever are not our own actions. [...] If you suppose that only to be your own which is your own, and what belongs to others such as it really is, then no one will ever compel you or restrain you.' [...] Marcus Aurelius, Meditations 4.3: 'Men seek retreats for themselves, houses in the country, seashores, and mountains... But it is in your power whenever you shall choose to retire into yourself. For nowhere either with more quiet or more freedom from trouble does a man retire than into his own soul.' [...] Seneca, Letters 77: 'Let us prepare our minds as if we had come to the very end of life. Let us postpone nothing. Let us balance life's books each day.' — Epictetus, Enchiridion; Marcus Aurelius, Meditations; Seneca, Letters from a Stoic; SEP 'Stoicism'”
