A word on the Jesus Prayer
The practice of prayer is called an ‘art’, and it is a very simple one. Standing with consciousness and attention in the heart, cry out unceasingly: 'Lord Jesus Christ, Son of God, have mercy upon me,' without having in your mind any visual concept or image, believing that the Lord sees you and listens to you.
It is important to keep your consciousness in the heart, and as you do so to control your breathing a little so as to keep time with the words of the prayer. But the most important thing is to believe that God is near and hears. Say the prayer for God’s ear alone.
At the beginning this prayer remains for a long time only an activity like any other, but in time it passes into the mind and finally takes root in the heart.
- St. Theophan the Recluse, The Jesus Prayer
