The mystery of prayer is not consummated at a certain specific time or place. For if you restrict prayer to particular times or places, you will waste the rest of the time in vain pursuits. Prayer may be defined as the intellect’s unceasing intercourse with God. Its task is to engage the soul totally in things divine, its fulfillment – to adapt the words of St Paul (cf. 1 Cor. 6:17) – lies in so wedding the mind to God that it becomes one spirit with Him.
