St. Nilus of Sora ca. 1443-1508
Learn something from the Scriptures by heart, keeping your mind focused on it. These things impede the demons from making incursions against us. This is also a stratagem of the Holy Fathers. (The Complete Extant Ascetical Works [in Greek] [Thessaloniki: Ekdoseis “Orthodoxos Kypsele,” 1985], pp. 229-230)
