This is the Second American Edition of The Enlargement of the Heart, now published with invaluable indexes (of Scriptural References and of Names and Subjects). Already regarded as a classic, The Enlargement of the Heart consists of a series of remarkable presentations on the nature and purpose of human existence in Saint Silouan the Athonite (1866-1938) and Elder Sophrony of Essex (1896-1993), and an Appendix comprised of two lectures on Monasticism. Delivered in Wichita, Kansas, at the 2001 Clergy Brotherhood Retreat of the Antiochian Orthodox Christian Church, each lecture is published here in full together with its Asides and corresponding Questions & Answers.
