Essentially, prayer is attentiveness to God, and this has various degrees, from weak or faltering to total. This attentive attitude is itself the fruit of love; God's love becomes the dominant commitment of the will. The person has achieved purity of heart and spiritual wholeness. Joy takes hold of the heart, transmuting every moment into the irresistible attraction and power of divine love.
At a certain point you say to the woods, to the sea, to the mountains, the world: Now I am ready. Now I will stop and be wholly attentive. You empty yourself and wait, listening ... you wait, you give your life's length to listening.
