In a quiet room (perhaps after some spiritual reading, or after lighting a small oil lamp in front of the icons and burning incense), as far as possible away from noise and activity, and after other considerations and thoughts have fallen quiet, they should sink their nous into the heart by saying the prayer: “Lord Jesus Christ, have mercy on me, a sinner.” How much peace and strength the psyches draw from the silence of God! How much this strengthens them during the day so that they can keep themselves peaceful without nervous tension and anxiety, but have all their forces united in harmony!
