This work, incorporating previously unpublished interviews and articles, retraces the quest of Henry Corbin into the imaginal realm of the unseen self, the domains of angels and numinous beings. A study of religious philosophy, exploration of visionary faith, these pages offer a superb meditation of the great themes of Perso-Islamic mysticism—the Sufi theory of knowledge, the voyage within the soul, —and an illuminating glimpse into the philosophic universes of Sohravardi, Ibn Arabi, and Molla Sarda Shirazi.
