Translation of the words of Isaac Sirin into Church Slavonic In the 18th century, it was not only the result of the numerous aspirations of the monastic circle, but also the result of the irrepressible desire of Paisius Velichkovsky to make patristic thought available. This book can truly be called the sister of Slavic Kindness. The translation of Elder Paisius was the most accurate, verified. The elder writes about this in the preface of this book in detail. Unfortunately, the book was published in small print runs only in 1812, after the death of the elder, and then received a new birth only in 1854 in the possessions of the optina desert.
