Prayer is the subject of conferences 9 and 10 and its importance is underlined at the very beginning of the 9th: "The end of every monk and the perfection of his heart incline him to constant and uninterrupted perseverance in prayer." But this constant prayer demands, in turn, perfection of heart and the virtues that go with it. This ninth conference serves as a kind of preliminary, among other things establishing the conditions for prayer and the different possible characteristics of prayer.
