Ladder of Divine Ascent — Step by Step to God

The Klimax (Ladder of Divine Ascent) by John Climacus is a 7th-century monastic manual prescribing thirty steps (bathmoi) from renunciation of the world to the summit of agape, with each rung requiring mastery of a specific vice or cultivation of a specific virtue. The structure is explicitly sequential: the monk cannot ascend to dispassion (apatheia) without first passing through obedience, penitence, and the remembrance of death (mneme thanatou). Climacus wrote it for the monks of Sinai, and its authority in Eastern monasticism is second only to Scripture — it is read aloud every Great Lent in Orthodox communities as a map of the soul's ascent to theosis.
