This volume contains three of Jan van Ruysbroeck's best works: The Adornment Of The Spiritual Marriage; The Book Of Truth; and The Sparkling Stone. These works were remarkable for their combination of lofty spiritual philosophy and robust common sense. As we read them, we feel that we are in touch with a man who never, in his ascents to God, loses hold on the actualities of human life. In The Adornment Of The Spiritual Marriage, he traces the gradual development of the soul, through the active life of Christian virtue, the interior life of contemplation and the superessential life of union with God. The Sparkling Stone further elaborates some of the more difficult passages in The Adornment, and The Book Of Truth was written as a refutation of the accusation that his work supported a pantheistic and heretical view of the union of soul with God. St. Paul and St. Augustine were van Ruysbroeck's primary influences and he was driven to speak out on the mystical life in reaction to the rising of heretical sects in the lowlands of Belgium early in the 14th century that were preaching a quietism of the most soul-destroying kind. The singular feature of his teaching is achieving a balanced career of action and contemplation as the ideal of the Christian soul.
