This treatise is a detailed interpretation and a mystic application of the text adapted from Wisdom x. 10: _Justum deduxit Dominus per vias rectus et ostendit illi regnum Dei_ in the Breviary Office of a Confessor. Upon these words Ruysbroeck bases a division of his work into five books. The first book treats of God, _Dominus_, His power and sovereignty. In the second Blessed John explains how Christ conducted, _deduxit_, man into the liberty of the children of God, chiefly by redemption and by the institution of the seven Sacraments. In the third he treats of the just man, _justum_, and works out eight items which render a man just, both in the active and in the contemplative life. The fourth book expounds the right ways, _vias rectas_, which lead to the Kingdom of God: _the exterior way_, namely, the material universe of three heavens and four elements, the contemplation of which should excite man to the praise of the Creator; _the way of natural light_, the acquisition of the seven virtues; finally, _the supernatural and divine way_, the infusion of the supernatural virtues and the gifts of the Holy Ghost. In the last book we have a disquisition on the kingdom of God, _ostendit illi regnum Dei_, of which we are told there are five aspects or divisions: the sensible kingdom, exterior to God, in which the author finds scope for a description of the last judgment and the qualities of risen bodies, the kingdom of nature, the kingdom of the Scriptures, the kingdom of grace and of glory, and finally the Divine Kingdom itself, which is God. This treatise is full of reflections and considerations of the most elevated order, and there is much therein that is by no means easy to grasp or understand. The Splendour of the Spiritual Espousals
