How to free thousands of souls from Purgatory

A common rosary crown is used.

On large grains, this prayer is said:
Eternal Father, I offer the Precious Blood of Your Divine Son, Jesus, in union with the Masses said all over the world, today, for all the holy Souls of Purgatory for sinners everywhere, for sinners of the universal Church, those of my home and within my family. Amen

Our Lord told Saint Geltrude the Great that the following prayer would free a thousand souls from Purgatory whenever it is said with love.

On small grains is recited this ejaculatory:
Holy Mother of God, Coredemptrix of the world, Pray for us

Extract from the 41st message of the MOTHER OF GOD, revealed on February 12, 1998 in Fulda (Germany) to the seer Anna, who makes hidden life.
... in all Holy Masses, together with my beloved Son, I pray for you, I offer myself for you. This is why my Son wants humanity not only to recognize me as DIE OF GOD, which is the greatest honor, but also as CORREDENTRICE of the world. And this is my very venerable middle name. One day the Pope will proclaim this dogma all over the world, that is that MARY the Mother of GOD, is also CORREDENTRICE of the world. Invoke me as much as you can in your prayers - CORREDENTER - and I will bestow upon you many graces which are necessary for your and others' liberation.
There is little time and in Purgatory there are many poor Souls ... We must save them.
If a man prays with pity and with an open heart this brief prayer, this insistent ejaculation: "Mother of God, Coredemptrix of the world, Pray for us" free every time she is recited, a thousand Souls from Purgatory. You can say this prayer anywhere - on foot or by car, in church, at home, on the street - anywhere.
