A method of quiet meditation in which a single symbolic word is used as a sign of one’s willingness to wait on God and be available to God’s presence. This word is used as a point of focus. The discipline involves setting aside twenty minutes or so for quiet prayer. This apophatic method has been widely taught and practiced in the Episcopal Church since the early 1980s. Thomas Keating’s Finding Grace at the Center (1978) encouraged the practice of centering prayer.
