Edith Stein (St. Theresa Benedicta) has an interesting discussion in her Science of the Cross about the voice of the heart or the center point. This center of ourselves is where G_d resides; it is a point from which we operate with complete freedom to be entirely ourselves as we were created to be. It is also a point that we mostly do not perceive or reach - according to Edith Stein we are mostly controlled and make choices due to outside influences - outside of our real selves, that is. In order to reach the voice of the heart or the center point we must determine to act with truth and in truth in all that we do; this determination of the will is the key to knowing our true center, our true selves, and so having the ability to be free in our choices.
I believe that Christotherapy would agree with the above and that the goal of Christotherapy would be to lead one to one's center point so that one can hear the voice of one's heart.
