§7.64.1Ἐπὶ μὲν παντὸς πόνου πρόχειρον ἔστω ὅτι οὐκ αἰσχρὸν οὐδὲ τὴν διάνοιαν τὴν κυβερνῶσαν χείρω ποιεῖ· οὔτε γὰρ καθὸ λογική ἐστιν οὔτε καθὸ κοινωνικὴ διαφθείρει αὐτήν.
In the case of every pain, let this be at hand: that it is not shameful, nor does it make the ruling mind worse; for it does not destroy it, neither insofar as it is rational nor insofar as it is social.
ἐπὶ μέντοι τῶν πλείστων πόνων καὶ τὸ τοῦ Ἐπικούρου σοι βοηθείτω, ὅτι οὔτε ἀφόρητον οὔτε αἰώνιον, ἐὰν τῶν ὅρων μνημονεύῃς καὶ μὴ προσδοξάζῃς.
However, in the case of most pains, let the saying of Epicurus also help you: that pain is neither intolerable nor everlasting, if you bear in mind its limits and do not add opinion to it.
κἀκείνου δὲ μέμνησο, ὅτι πολλὰ πόνῳ τὰ αὐτὰ ὄντα λανθάνει, δυσχεραινόμενα· οἷον τὸ νυστάζειν καὶ τὸ καυματίζεσθαι καὶ τὸ ἀνορεκτεῖν·
And remember this too: that many things which are the same as pain escape our notice, though they are felt as disagreeable—for example, drowsiness, being overheated, and loss of appetite.
ὅταν οὖν τινι τούτων δυσαρεστῇς, λέγε ἑαυτῷ, ὅτι πόνῳ ἐνδίδως.
Therefore, whenever you are dissatisfied with any of these, say to yourself: "You are giving way to pain."
