A clean, unmarked copy which has only slight usage wear. “Centering Prayer is the path to a wonderful and radical new way of seeing the world. It is not, as sometimes thought, simply an act of devotional, piety, nor is it simply 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 perception of non-duality.”
