Epictetus, Encheiridion 15
“Remember that it is right to act as if you are at a dinner party. When something is passed around to you, reach out and take a little kindly. It moves on. Don’t hold it. When it hasn’t made it to you yet, don’t express that you want it, but be patient.
Act the same way toward children, a spouse, and wealth. Then, someday you will be worthy of a dinner with the gods. Yet, if you do not take these things when they are offered, but instead look down on them, you will not merely be a dinner guest of the gods, but you will host with them too. This is how Diogenes and Heraclitus behaved along with other men who were similarly divine and rightly called so.”
c. 15. Μέμνησο, ὅτι ὡς ἐν συμποσίῳ σε δεῖ ἀναστρέφεσθαι. περιφερόμενον γέγονέ τι κατὰ σέ· ἐκτείνας τὴν χεῖρα κοσμίως μετάλαβε. παρέρχεται· μὴ κάτεχε. οὔπω ἥκει· μὴ ἐπίβαλλε πόρρω τὴν ὄρεξιν, ἀλλὰ περίμενε, μέχρις ἂν γένηται κατὰ σέ. οὕτω πρὸς τέκνα, οὕτω πρὸς γυναῖκα, οὕτω πρὸς ἀρχάς, οὕτω πρὸς πλοῦτον· καὶ ἔσῃ ποτὲ ἄξιος τῶν θεῶν συμπότης. ἂν δὲ καὶ παρατεθέντων σοι μὴ λάβῃς, ἀλλ᾿ ὑπερίδῃς, τότε οὐ μόνον συμπότης τῶν θεῶν ἔσῃ, ἀλλὰ καὶ συνάρχων. οὕτω γὰρ ποιῶν Διογένης καὶ Ἡράκλειτος καὶ οἱ ὅμοιοι ἀξίως θεῖοί τε ἦσαν καὶ ἐλέγοντο.
