Spirituality in human beings is not an extra or "superior" mode of existence. It's not a hidden stream of separate reality, a separate life running parallel to our bodily existence. It does not consist of special "inward" acts even though it has an inner aspect. It is, rather, a relationship of our embodied selves to God that has the natural and irrepressible effect of making us alive to the Kingdom of God—here and now in the material world.
