As the most precious of all the senses is sight, so the most divine of all the virtues is prayer. St. Neilos
Great spiritual figures have been nourished by this text and have used it as public spiritual nourishment, by deed and word, for generations and generations of monks and faithful Christians. In this way the holy predecessor of more recent times, St. Nikodemus of the Mount Athos, found this text very suitable for the spiritual nourishment of Orthodox monks and Christians and for their guidance, and included it in the famous collection of the Philocalia.
