The Spiritual Canticle is one of St John's greatest works. Using the simple metaphor of the spouse and the bride, he sketches a series of dialogues between God and the soul, rihc in natural imagery. The fragrant vineyards, fruitful valleys and green hills, flocks of sheep and clear streams all speak of the Object of mystical love. The imahes of the basic Spiritual Canticle are so beautiful and its music so captivating that many who first heard it begged St John to write a commentary, together with its profound reflections on the relations of the soul to God, has become one of the world's richest sources of meditation. The commentary and the sublime poetry that inspired them form what is presented here as the complete Spiritual Canticle.
