For prayer is a supernatural activity or nothing at all; and it must primarily be directed to supernatural ends. It too acknowledges the soul’s basic law: it comes from God, belongs to God, is destined for God. It must begin, end, and be enclosed in the atmosphere of adoration; aiming at God for and in Himself. Our ultimate effect as transmitters of the supernal light and love directly depends on this adoring attentiveness.
— Evelyn Underhill, Concerning the Inner Life
