Catholicism is the big house of Christianity. It's got many, many rooms in it. And I've always been attracted to the rooms which are to do with prayer. The mystical strain is the strain whereby the whole day can be given over to prayer through what we call lectio divina, prayerful reading of Scripture, through practice of meditation of when one uses the imagination and the intellect with respect to images, and then finally, and most difficult of all, contemplation, where one empties the mind of all images and all ideas, all concepts, in order to be completely attentive to God.
