In meditative prayer, one thinks and speaks not only with his mind and lips, but in a certain sense with his whole being. Prayer is then not just a formula of words, or a series of desires springing up in the heart - it is the orientation of our whole body, mind, and spirit to God in silence, attention, and adoration. All good meditative prayer is a conversion of our entire self to God.
One cannot then enter into mediation, in this sense, without a kind of inner upheaval. By upheaval I do not mean a disturbance, but a breaking out of routine, a liberation of the heart from the cares and preoccupations of one's daily business.
