On the Prayer of Jesus: The Classic Guide to the Practice of Unceasing Prayer Found in The Way of a Pilgrim;

Thousands have fallen in love with the anonymously authored book The Way of a Pilgrim—the account of an ordinary man's encounter with the Eastern Orthodox Christian practice of the Jesus Prayer, which consists of the constant repetition of the short phrase, "Lord Jesus Christ, have mercy upon me." Here is the perfect introduction to this life-changing practice, as it was taught by one of the great spiritual lights of Russia. Bishop Ignatius Brianchaniov (1807–1867) provides wise instruction and advice covering all aspects of the practice, from how to get started, to approaching difficulties that arise, to dealing with friends and family who don't get what you're doing, to making this prayer (also called the Prayer of the Heart) the foundation of your life.
