That We May Be One – Christian Non-Duality, with Fr. Thomas Keating. This book is an edited transcript of the DVD series of the same name which continues and builds on the works of Thomas Keating over the past 30+ Years. Opening to the Divine Indwelling through practicing Centering Prayer is the consent to God's presence and action within us. This separate-self sense gradually evolves into the conviction of self in God. Includes beautiful images throughout.
