O holy souls in Purgatory, thou are the certain heirs of Heaven. Thou are most dear to Jesus, as the trophies of His Precious Blood and to Mary, Mother of Mercy. Obtain for me, through thine intercession, the grace to lead a holy life, to die a happy death and to attain to the blessedness of eternity in Heaven.
Dear suffering souls, who long to be delivered in order to praise and glorify God in Heaven, by thine unfailing pity, help me in the needs which distress me at this time, particularly (here mention your request), so that I may obtain relief and assistance from God.
In gratitude for thine intercession, I offer to God on thy behalf the satisfactory merits of my prayers, works, joys and sufferings of this day (week, month, or whatever space of time you wish to designate). Amen.
