§4.18.1Ὅσην εὐσχολίαν κερδαίνει ὁ μὴ βλέπων τί ὁ πλησίον εἶπεν ἢ ἔπραξεν ἢ διενοήθη, ἀλλὰ μόνον τί αὐτὸς ποιεῖ, ἵνα αὐτὸ τοῦτο δίκαιον ᾖ καὶ ὅσιον ἢ † κατὰ τὸν ἀγαθὸν·
How much leisure does he gain who does not look at what his neighbour has said or done or thought, but only at what he does himself, in order that this very thing may be just and holy, or in accordance with the good man.
μὴ μέλαν ἦθος περιβλέπεσθαι, ἀλλʼ ἐπὶ τῆς γραμμῆς τρέχειν ὀρθόν, μὴ διερριμμένον.
Do not look around at a dark character, but run straight along the line, without being distracted.
