Chaplet of St. Gertrude

Many souls are released from purgatory praying this prayer, Our Lord showed St. Gertrude. 

Using rosary beads:

Pray the Apostle's Creed, 1 Our Father, 3 Hail Marys, and 1 Glory Be.
For the decades pray the Our Father and Glory Be as usual.

On the Hail Mary beads pray:

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.

Replace the Fatima prayer with:

Most Sacred Heart of Jesus, open the hearts and minds of sinners to the truth and light of God, the Father. Immaculate Heart of Mary, pray for the conversion of sinners and the world.
