From the website of Holy Trinity Publications:

This modest work is an anthology of spiritual advice given by various of the nineteenth-century Holy Elders of Optina Monastery, organized thematically under headings such as spiritual warfare, the love of neighbor, faith, the will of God, the education of children, the commandments of God, the path of salvation, etc. Each piece of advice varies in length from a single sentence to a full paragraph. Pithy, immediately accessible, and universally applicable, these counsels resemble the sayings of the ancient Desert Fathers. Appropriate both for prolonged study and for daily devotional reading.
