The great mystics are the paradigms and the amplifiers of a life of deep faith, hope, and love. They help us to hear the interior whispers and to see the faint flickers of truth and love in ourselves and others. By looking at their lives, we can frequently discover the obstacle in us to fully authentic human life. Looking into the lives of the great mystics will help to locate the compass of our hearts, to see what authentic human living is, and what our final purification, illumination, and transformation entail.
