Вместо предисловия. Предлагаемые Письма о духовной жизни составлены по поводу писем графа М. М. Сперанского, напечатанных в "Русском Архиве" за 1870 год, в январской книжке.
Я имел намерение представить картину духовной жизни в разнообразных ее оттенках. Письма Сперанского служили только поводом к тому. Желание было одно, чтоб ревнующим о духовной жизни представить от¬части некоторые нужные указания, а отчасти дать случай самим заняться теми же предме¬тами и обдумать их поприложимее к себе самим.
St. Theophan the Recluse, also known as Theophan Zatvornik or Theophanes the Recluse (Russian: Феофан Затворник), is a well-known saint in the Russian Orthodox Church. He was born George Vasilievich Govorov, in the village of Chernavsk. His father was a Russian Orthodox priest. He was educated in the seminaries at Livny, Orel and Kiev. In 1841 he was ordained, became a monk, and adopted the name Theophan. He later became the Bishop of Tambov.
He is especially well-known today through the many books he wrote concerning the spiritual life, especially on the subjects of the Christian life and the training of youth in the faith. He also played an important role in translating the Philokalia from Church Slavonic into Russian. The Philokalia is a classic of orthodox spirituality, composed of the collected works of a number of church fathers which were edited and placed in a four volume set in the 17th and 18th centuries. A persistent theme is developing an interior life of continuous prayer, learning to "pray without ceasing" as St. Paul teaches in his first letter to the Thessalonians.
