"The blessed and immortal nature knows no trouble itself, nor causes trouble to any other, so that it is never constrained by anger or favor. For all such things exist only in the weak." Epicurus PD1 (Bailey)
1 Τὸ μακάριον καὶ ἄφθαρτον οὔτε αὐτὸ πράγματα ἔχει οὔτε ἄλλῳ παρέχει· ὥστε οὔτε ὀργαῖς οὔτε χάρισι συνέχεται· ἐν ἀσθενεῖ γὰρ πᾶν τὸ τοιοῦτον.
Saint-Andre translation: 1 That which is blissful and immortal has no troubles itself, nor does it cause trouble for others, so that it is not affected by anger or gratitude (for all such things come about through weakness).
