Attending To The World And Heaven

Οὐκ ἔστιν ἁμαρτία τὸ πρὸς βραχὺ προσελθεῖν τῇ καθ' ἡμέραν τροφῇ ἐν τῇ τεταγμένῇ ὥρᾳ. Χρὴ δὲ λοιπὸν μετὰ τὸ προσταπεινωθῆναι τῇ χρείᾳ τοῦ σώματος, ὀξέως πάλιν εἰς τὸν οὐρανὸν κοῦφον ἀναπέμπειν τὸ φρόνημα, μηδὲν ἐν αὐτῷ συνανακουφίζων τῶν χοῖνῶν φροντισμάτων. Ἅγιος Νειλος, Βιβλιον Δεύτερος, Ἐπιστολὴ ΝΘ' Χαριτονι Μοναχῳ Source: Migne PG 79.225c

It is no sin to go swiftly every day to food at the appointed hour. But it is necessary that after lowering oneself to the necessity of the body that one quickly again lift up one's empty thoughts to heaven, in one's ascent having nothing of worldly concerns. Saint Nilus of Sinai, Book 2, Letter 59, to Charito The Monk
