§6.11.1Ὅταν ἀναγκασθῇς ὑπὸ τῶν περιεστηκότων οἱονεὶ διαταραχθῆναι, ταχέως ἐπάνιθι εἰς σεαυτὸν καὶ μὴ ὑπὲρ τὰ ἀναγκαῖα ἐξίστασο τοῦ ῥυθμοῦ· ἔσῃ γὰρ ἐγκρατέστερος τῆς ἁρμονίας τῷ συνεχῶς εἰς αὐτὴν ἐπανέρχεσθαι.
When you are forced, as it were, to be disturbed by your surroundings, quickly return to yourself, and do not fall out of the rhythm more than is necessary; for you will be more master of the harmony by continually returning to it.
