Symeon the new theologian1980

"This great master of Eastern Christianity was an abbot, spiritual director of renown, theologian and important Church reformer. These 'Discourses' which form the central work of his life, were preached by St. Symeon to his monks during their morning Matins ritual. They treat such basic spiritual themes as repentance, detachment, renunciation, the works of charity, impassibility, remembrance of death, sorrow for sins, the practice of God's commandments, mystical union with the indwelling Trinity, faith and contemplation." -- Back cover.
