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.
Certain redwood groves are holy places for me because they capture silence and light. The forest is so dense as to exclude all external noise. It is possible to ignore their silence until a single bird sings within. When the single song has died not only do I realize I have heard a sound exquisite in its simplicity, but also that I have heard it so precisely because it was embedded in pure silence.
