Piero Ferrucci, Ineffable Grace (p.254) quoted in Centering Prayer and Inner Awakening, by Cynthia Bourgeault,
I've returned to 'practicing' meditation. I'd like to say 'trying,' not 'practicing,' but I know how that word can imply failure. When we try, we hope for success but know that failure is always a possibility. When we try, our endeavor ends and we go on to something else.
When we practice, however, failure or success isn't a part of it. We keep going, sometimes being in the moment, sometimes being some place else, sometimes being with God, sometimes with some else.
The goal in practicing centering prayer is to be totally open to God, which has not no end. That's what I'm practicing.
