“God’s first word is silence.” -Thomas Keating Centering Prayer is a method of silent prayer that prepares us to receive the gift of contemplative prayer, prayer in which we experience God's presence within us, closer than breathing, closer than thinking, closer than consciousness itself. This method of prayer is both a relationship with God and a discipline to foster that relationship. Centering Prayer is not meant to replace other kinds of prayer; rather it casts a new light and depth of meaning on them. Centering Prayer is an ancient method of Christian prayer adapted for modern times by Fathers Thomas Keating, William Meninger and Basil Pennington. The Centering Prayer application will support your daily prayer practice commitment. Beautiful and peaceful, the app includes an adjustable timer, as well as opening and closing prayer options that you may read before and after your silent prayer time. An assortment of sounds and backgrounds allow you to choose the type of environment you want to create for your prayer time. Brief instructions for learning Centering Prayer are also included. It is recommended you practice being in relationship with God through Centering Prayer twice a day for 20 minutes to begin with.
