This also was addressed to a nun, probably the same Poor Clare. It explains again the three degrees of the mystic life, but with special reference now to the cloister and the Blessed Eucharist. Some are in the purgative way: if they persevere in virtue and progress in perfection, they shall partake of the table, Ps. xxiii. 5, which is no other than the banquet of the Holy Eucharist. Ruysbroeck dwells on the virtues necessary for the worthy reception of the Sacrament, and narrates the manner of its institution by our Divine Lord at the Last Supper, showing what were the matter and form used by Christ. He discourses on the evidence of God's love to be found in this mystery of the altar; and then refutes objections as to the manner of the Divine Presence, expressly teaching Transubstantiation. Those who approach the altar rails are divided by him into seven classes, and here the author shows a wondrous and intimate knowledge of the working of the human heart. The treatise closes with a description of the contemplative life. The Seven Degrees of Spiritual Love In a simile familiar to spiritual writers of all ages, Ruysbroeck compares life to a ladder, or stairway of seven steps, leading up to perfection and union with God. These stages are respectively: (1) Conformity with the holy will of God; (2) Voluntary poverty; (3) Purity of soul and chastity of body; (4) Humility, with her four daughters, obedience, gentleness, patience, and the forsaking of self-will; (5) The desire of the divine glory, involving three spiritual exercises, namely, acts of love and adoration, acts of supplication, and acts of thanksgiving; (6) The contemplative and perfect life, by which man finally attains the last stage of, (7) sublime ignorance.
