Prayer begins in us the restoration of the divine image, in all its hiddenness and wonder. It brings us closer to the "region of likeness" and every prayer is an act of letting the old self go. It involves "dying". The grain of wheat falls into the ground and dies. Dead, it is destined to bear much fruit.
Love has to go through darkness and pain and endurance and a stark acceptance before it can come out into the far light of the sun.
