The existence of purgatory — where all those souls who die in the state of sanctifying grace and yet still have to undergo a period of purgation before entering the kingdom of God, because according to Scriptures nothing sin will enter heaven — is a dogma of our Catholic faith.
This is how St. Faustina described purgatory: "I was in a misty place full of fire in which there was a great crowd of suffering souls. They were praying fervently for themselves but to no avail for only we can come to their aid. The flames which were burning them did not touch me at all. They answered me in one voice, that their greatest torment was longing for God."
She saw Our Lady visiting these souls. All the Holy Souls in purgatory call her "The Star of the Sea." As she was leaving, St. Faustina heard a voice say to her, "My mercy does not want this, but justice demands it."
The church teaches that once in purgatory, those souls cannot gain any more merit to help themselves. They rely on our charity, our prayers, our sufferings and our sacrifices. But even if we should forget those in purgatory, Our Lady cannot forget them because she loves all her children, especially those who need her most.
Our Lady once said to St. Bridget, "I am the Mother of all the souls in purgatory, and I am Mother of Mercy to these my children who are in the greatest need of my assistance, since in their torments they cannot help themselves."
St. Bernardine of Siena says "that in that prison where souls that are spouses of Jesus Christ are detained, Mary has a certain dominion and plentitude of power not only to relieve them but even to deliver them from their pains."
Again, she told St. Bridget that as a compassionate Mother, she condescends to go herself often into that Holy Prison to visit and comfort her suffering children.
To her children who are devoted to the recitation of the Holy Rosary every day, Our Lady promises "to personally deliver them from purgatory herself." That promise is pictured in the painting of the Last Judgment by Michelangelo, where Our Lady is seen pulling two souls out of purgatory by means of the chain of the Holy Rosary.
And how about Our Lady's second great scapular promise known as the "Sabbatine Privilege," which was given by the Blessed Virgin Mary to Pope John XXII in the year 1322: "Those who wear the Scapular and fulfill two other conditions (Chastity and Prayer) can obtain early liberation from Purgatory, through the special intercession of the Virgin Mary, on the first Saturday after their death, the day consecrated to her."
St. Bernadine of Siena said the Blessed Virgin has the power of delivering souls from purgatory, but more particularly those who were most devoted to her.
The church teaches that the Holy Sacrifice of the Mass is the most effective means of assisting souls in purgatory. Another effective means is reciting the rosary. By the rosary, we offer to God all the merits of Our Lord in union with Mary for the suffering souls.
How much it must please Our Lady when we offer the rosary in union with her to liberate her suffering children from that holy prison to be with her in heaven, and in the process, she promises to also liberate us from that prison to be with her forever.
