Amor fati. Marcus Aurelius 4.39

Stoic resignation teaches adepts to make evil a personal choice, something we take up in addition to whatever happens (which may appear good or bad to us or the world: it does not matter). If you refuse to take evil from disaster, then its wickedness is turned to your good, building your character rather than breaking it. Building character is the ultimate end of Stoicism: staying comfortable, or even alive, is not as important.

Ἐν ἀλλοτρίῳ ἡγεμονικῷ κακὸν σὸν οὐχ ὑφίσταται οὐδὲ μὴν ἔν τινι τροπῇ καὶ ἑτεροιώσει τοῦ περιέχοντος. ποῦ οὖν; ὅπου τὸ περὶ κακῶν ὑπολαμβάνον σοί ἐστι. τοῦτο οὖν μὴ ὑπολαμβανέτω καὶ πάντα εὖ ἔχει. κἂν τὸ ἐγγυτάτω αὐτοῦ, τὸ σωμάτιον, τέμνηται, καίηται, διαπυίσκηται, σήπηται, ὅμως τὸ ὑπολαμβάνον περὶ τούτων μόριον ἡσυχαζέτω· τουτέστι, κρινέτω μήτε κακόν τι εἶναι μήτε ἀγαθόν, ὃ ἐπίσης δύναται κακῷ ἀνδρὶ καὶ ἀγαθῷ συμβαίνειν. ὃ γὰρ καὶ τῷ παρὰ φύσιν καὶ τῷ κατὰ φύσιν βιοῦντι ἐπίσης συμβαίνει, τοῦτο οὔτε κατὰ φύσιν ἐστὶν οὔτε παρὰ φύσιν.

No alteration in the state of the universe can transplant the evil unique to your character into the mind of another: there is no way for it to take hold there. How so? The faculty of grasping evil is unique to the person: your conception of wrong belongs to you as something special, a power only you can wield. Refuse to exercise it, and all is well. Even if your body, the thing closest to your soul's faculty for evil, be cut, burned, festering, rotten, still you must keep the mind from grasping after evil: keep it quiet. Make it deem nothing good or evil that can happen as easily to a good man as a bad one. Whatever befalls us regardless of our choices, which can be against nature or in harmony with her, is in itself neither a denial of nature nor an affirmation of her.
