Spiritual Theology's journey through these last decades shows an itinerary of development, the fruit of which is an ever more solid identity. This book seeks to present a perspective in that itinerary and in tune with the signs of our times: on one hand, militant secularism and, on the other, a widespread, concrete resurgence of experiences of transcendence. In this sense, I am presenting a path of study organized around five concepts: presence, mystery, transcendence, lived experience, and transformation. In effect, the inner transformation worked by the Presence of Mystery leaves a new knowing, in which the relationship with reality is renewed, since it has expanded and dilated beyond sensible perception, opening the subject up to an unlimited and real horizon of transcendence. The awareness of perceiving a 'greater reality' within reality leaves an emotional resonance that teaches a new way of feeling and reacting in the face of sensibly perceived reality.
