Enchiridion · §15

μέμνησο ὅτι ὡς ἐν συμποσίῳ σε δεῖ ἀναστρέφεσθαι. περιῆλθέν τι καὶ ἦλθεν ἐπί σε· ἔκτεινον τὴν χεῖρα καὶ λαβὲ κοσμίως. παρῆλθεν; μὴ κάτεχε. οὔπω ἦλθεν; μὴ ἐπίβαλλε πόρρω τὴν ὄρεξιν, ἀλλὰ περίμενε μέχρις ἂν ἔλθῃ πρὸς σέ. οὕτω πρὸς τέκνα, οὕτω πρὸς γυναῖκα, οὕτω πρὸς ἀρχάς, οὕτω πρὸς πλοῦτον· καὶ ἔσῃ ποτε ἄξιος συμπότης τῶν θεῶν.

memnēso hoti hōs en sumposiō se dei anastrephesthai. periēlthen ti kai ēlthen epi se; ekteinon tēn cheira kai labe kosmiōs. parēlthen? mē kateche. oupō ēlthen? mē epiballe porrō tēn orexin, alla perimene mechris an elthē pros se.

Remember that you must behave as you would at a banquet. Something is carried around and comes to you: reach out your hand and take your portion with grace. It passes by: do not hold it back. It has not yet arrived: do not reach forward with desire, but wait until it comes to you. So it is with children, with a wife, with public office, with wealth. And one day you will be worthy to dine with the gods.
