The Ladder of Divine Ascent (Lestvitsa)
Лествица
Written by the sixth-century abbot of the Sinai monastery, the Ladder of Divine Ascent presents a 30-step progression from renunciation of the world to the summit of love, using precise psychological observation to diagnose and cure the passions. A personal copy with red and gold embossed cover, inscribed 'A.F. Ts.S. March 1906,' was documented among Empress Alexandra's books recovered at Ekaterinburg, with multiple bookmarks and pencil annotations throughout. The Church of the Ladder (Tserkov Rizopolozheniya) within the Moscow Kremlin, built 1329, bears witness to the text's central role in Russian spiritual life across the entire Romanov dynasty. Its sustained use in the Eastern monastic tradition makes it one of the most closely studied works of practical spiritual theology in Orthodox Christianity.
