“Prayer is not divided dogmatically into types and methods but, according to our Fathers, every type and method of prayer is beneficial, as long as it is not of diabolic delusion and influence. The goal of this all-virtuous work is to turn and keep the mind of man on God. For this purpose our Fathers devised easier methods and simplified the prayer, so that the mind might more easily and more firmly turn to and remain in God. With the rest of the virtues other parts of man’s body come into play and senses intervene, whereas in blessed prayer the mind alone is fully active; thus much effort is needed to incite the mind and to bridle it, in order that the prayer may become fruitful and acceptable. Our most holy Fathers, who loved God in the fullest, had as their chief study uniting with God and remaining continuously in Him; thus they turned all of their efforts to prayer as the most efficient means to this end.”
