Περισκοπεῖν ἄστρων δρόμους ὥσπερ συμπεριθέοντα καὶ τὰς τῶν στοιχείων εἰς ἄλληλα μεταβολὰς συνεχῶς ἐννοεῖν· ἀποκαθαίρουσι γὰρ αἱ τούτων φαντασίαι τὸν ῥύπον τοῦ χαμαὶ βίου. | Watch the stars in their course as one that runneth about with them therein; and think constantly upon the reciprocal changes of the elements, for thoughts on these cleanse away the mire of our earthly life. |
