Father Thomas Keating, answering a life calling, sought to renew a prayer practice that goes beyond asking for aid or offering praise—one that invites you to enter into a deeper relationship with God. Based on the wisdom sayings of Jesus and inspired by teachings from the classic 14th-century text The Cloud of Unknowing, Saint John of the Cross, Saint Teresa of Avila, Thomas Merton, and others, Centering Prayer is a method of four guidelines that has sparked the modern renewal of contemplative Christianity. "Centering Prayer does not replace other types of prayer," teaches Keating. "Rather, the practice gives a new depth of meaning to all forms of prayer."
