On the Mystical Life Set

This three volume set of the Ethical Discourses of St Symeon the New Theologian includes: Volume I: The Church and the Last Things; Volume II: On Virtue and the Christian Life; Volume III: Life, Times and Theology. Each volume is also sold separately. 

St Symeon the New Theologian was abbot of the monastery of St Mamas in Constantinople at the turn of the eleventh century. He was also perhaps the most remarkable and certainly the most forceful advocate of the mystical experience of God in the history of the Byzantine Church.
