The Unpublished Manuscript of Purgatory
https://amzn.to/4iBhNJQ

Eternal Father, I offer Thee the Most Precious Blood of Thy Divine Son, Jesus, in union with the masses said throughout the world today, for all the holy souls in purgatory, for sinners everywhere, for sinners in the universal church, those in my own home and within my family. Amen.

Official Act of Consecration to Mary
Written by St. Maximilian Kolbe

O Mary Star of the Sea, Queen of Heaven and Purgatory , refuge of sinners and our most loving Mother, God has willed to entrust the entire order of mercy to you.  I, (name), a repentant sinner, cast myself at your feet humbly imploring you to take me with all that I am and have, wholly to yourself as your possession and property.  Please make of me, of all my powers of soul and body, of my whole life, death and eternity, whatever most pleases you.
If it pleases you, use all that I am and have without reserve, wholly to accomplish what was said of you: “She will crush your head,” and, “You alone have destroyed all heresies in the world.”  Let me be a fit instrument in your immaculate and merciful hands for releasing as many Souls from Purgatory as Possible, and thus help extend as far as possible the blessed kingdom of the most Sacred Heart of Jesus.  For wherever you enter, you obtain the grace of conversion and growth in holiness, since it is through your hands that all graces come to us from the most Sacred Heart of Jesus.

V. Allow me to praise you, O sacred Virgin.
R. Give me strength against your enemies.
