Purgatory represents the concept of a transitional, purifying state before entrance into Heaven. It is a realm of hope and painful refinement. In poetry, particularly in Dante's Purgatorio, it serves as a powerful metaphor for the soul's struggle toward perfection. It symbolizes the necessary suffering that leads to healing and holiness, the bittersweet nature of repentance, and the enduring bonds between the living and the dead who can be aided by prayers.

Purgatory, defined at the Councils of Florence and Trent, is a state of purification for those destined for heaven but not yet perfected; it reflects the belief that love must be refined to bear divine light; in poetry, purgatorial imagery—fire, waiting, cleansing tears—explores the necessary pain of moral and spiritual growth before union.
