In a statement that is both simple and profound, St. Teresa says: "Mental prayer is nothing else, in my opinion, but being on terms of friendship with God, frequently conversing in secret with Him who, as we know, loves us." (3) Genuinely simple and pure Christian souls have always been acquainted with this completely spontaneous and intimate prayer. A peasant who was questioned by the Cure of Ars on his manner of prayer, defined it admirably by saying: "I look at our Lord who is in the tabernacle, and He looks at me." This is indeed the commerce of friendship, by which the soul converses alone with God by whom it believes itself loved. This interior prayer, which was so often that of the first Christians in the catacombs, has always existed in profoundly humble and religious souls eager for God. The royal Psalmist was, most certainly, profoundly acquainted with this prayer when he wrote: "As the hart panteth after the fountains of water, so my soul panteth after Thee, O God. My soul hath thirsted after the strong living God. When shall I come and appear before the face of God?" (4) http://www.christianperfection.info/tta47.php
