A mystic is a person who is deeply aware of the powerful presence of the divine Spirit; someone who seeks, above all, the knowledge and love of God, and who experiences to an extraordinary degree the profoundly personal encounter with the energy of divine life. Mystics often perceive the presence of God throughout the world of nature and in all that is alive, leading to a transfiguration of the ordinary all around them. However, the touch of God is most strongly felt deep within their own hearts.
