Father Thomas Keating is the founder of the Centering Prayer movement, based on the retreat into the "inner room" mentioned by Jesus in Matthew 6:6, where the individual is able to meet God. From the book Manifesting God, Father Keating explores three parables-the Parable of the Great Banquet, the Parable of the Leaven, and the Parable of the Publican and the Pharisee-and their relation to contemplative prayer.
