Richard Rohr offers a prayer practice based on devotion to the Sacred Heart of Jesus and the Immaculate Heart of Mary:
Many have described prayer as bringing our thinking down into our heart. Next time a resentment, negativity, or irritation comes into your mind, for example, and you want to play it out or attach to it, consciously move that thought or person into your heart space… Within the heart, it’s much easier to surround thoughts and sensations with silence, with the warmth of your life-blood—which can feel like burning coals. In this place it is almost impossible to judge, create story lines, or remain antagonistic. You are in a place that does not create or feed on contraries but is the natural organ of life, embodiment, and love. Love lives and thrives in the heart space. It has kept me from wanting to hurt people who have hurt me. It keeps me every day from obsessive, repetitive, or compulsive head games. It can make the difference between being happy or being miserable and negative.
Could this be what we are really doing when we say we are praying for someone? Yes, we are holding them in our heart space. Do it in an almost physical sense, and you will see how calmly and quickly it works. Now, the Sacred Heart and the Immaculate Heart have been transferred to you. They are pointing for you to join them there. The “sacred heart” is then your heart too, a heart on fire with love and compassion for the world.
