We will travel the road of repentance correctly if, as we begin to give attention to the intellect, we combine humility with watchfulness, and prayer with the power to rebut evil thoughts. In this way we will adorn the chamber of our heart with holy and venerable Name of Jesus Christ as with a lighted lamp, and will sweep our heart clean of all wickedness, purifying and embellishing it. But if we trust only in our watchfulness and attentiveness, we shall quickly be pushed aside by our enemies. We shall be overturned and cast down by their extreme craftiness. We will become even more fully entangled in their nets of evil thought, and will readily be slaughtered by them, lacking as we do the powerful sword of the Name of Jesus Christ. For only this sword, swiftly turning in the undivided heart, is able to cut them down, to burn and obliterate them as fire the reed.
St. Hesychius the Presbyter, On Watchfulness and Holiness, 152
