Spirituality is the principle of psychic growth.
Human consciousness is the only living entity that can choose not to grow.
Psychically we grow cyclically.
Addiction is a sick psychle.
Emotions are the symptoms we have to read the spiritual malaise.
Faiths, religions, can enable this growth or, alternately, they can ice growth. So, the tradition itself, or whether there is a tradition at all, is not an indicator of usefulness.
Growth requires change, and physical catastrophe is a terrain of great change. A person who has become very ill must change, is already changed, and so the hospital is a vast and relentless vehicle/machine of change.
It’s the role of the chaplain to engage that change and direct it into transformation.
