Centering Prayer is the path to a wonderful and radical new way of seeing the world. It is not, as is sometimes thought, simply an act of devotional piety, nor is it a Christianized form of other meditation methods. Cynthia Bourgeault cuts through the misconceptions to show that Centering Prayer is in fact a pioneering development within the Christian contemplative tradition. She provides a practical, complete course in the practice and then goes deeper to analyze what actually happens in Centering Prayer: the mind effectively switches to a new operating system that makes possible the perception of nonduality.
