The acceptance of all that God has given us and the willingness to let it go - to give it back to him at a moment's notice - that's true human freedom.
One of the values of centering prayer is that you are not thinking about God during the time of centering prayer so you are giving God a chance to manifest. In centering prayer there are moments of peace that give the psyche a chance to realize that God may not be so bad after all. God has a chance to be himself for a change.
