O, Holy Souls in Purgatory, you are the most certain heirs of heaven. You are most dear to Jesus as the trophies of His Precious Blood and to Mary, mother of mercy. Obtain for me through your 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 your unfailing pity help me in the needs which distress me at this time, particularly (name your needs), so that I may obtain relief and assistance from God.

In gratitude for your intercession, I offer to God in your behalf the satisfactory merits of my prayer and work, my joys and sufferings of this day (week, month, or whatever space of time you wish to designate). Amen.

Attend Mass and have a Mass offered for them, if at all possible. Offerings of the Precious Blood and the Way of the Cross are also powerful means of helping them and obtaining their help.
