Ὥστε ὁ ἀγαπῶν τὸν πλησίον ὡς ἑαυτὸν οὐδὲν περισσότερον κέκτηται τοῦ πλησίον· - Basil of Caesarea

Ἀλλ' οὐ γὰρ ἱματίων ἕνεκεν οὐδὲ τροφῶν ὁ πλοῦτός ἐστι τοῖς πολλοῖς περισπούδαστος, ἀλλά τις ἐπινενόηται μεθοδεία τῷ διαβόλῳ, μυρίας τοῖς πλουσίοις δαπάνης ἀφορμὰς ὑποβάλλουσα, ὥστε τὰ περιττὰ καὶ ἄχρηστα ὡς ἀναγκαῖα σπου δάζεσθαι, μηδὲν δὲ αὐτοῖς ἐξαρκεῖν πρὸς τὴν τῶν ἀναλωμάτων ἐπίνοιαν.

Where is Christ, the King? In heaven, to be sure. Thither it behooves you, soldier of Christ, to direct your course. Forget all earthly delights. A soldier does not build a house; he does not aspire to possession of lands; he does not concern himself with devious, coin-purveying trade. … The soldier enjoys a sustenance provided by the king; he need not furnish his own, nor vex himself in this regard.

The very beginning of the soul’s purgation is tranquility, in which the tongue is not given to discussing the affairs of men, nor the eyes to contemplating rosy cheeks or comely bodies, nor the ears to lowering the tone of the soul by listening to songs whose sole object is to amuse, or to words spoken by wits and buffoons—a practice which above all things tends to relax the tone of the soul.
