According to tradition, St. Gertrude the Great was told by Our Lord that each time she piously recited the following prayer, it would release 1,000 souls (or a vast number) from their suffering in purgatory:
Eternal Father, I offer You 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, for those in my own home, and in my family. Amen.
St. Gertrude the Great was a 13th-century German nun, writer, and mystic who was graced with many heavenly visions, including being one of the earliest mystics to whom Jesus encouraged a devotion to his Sacred Heart. It is recounted that Jesus showed her a vast number of souls entering heaven from purgatory as a result of her faithful and frequent recitation of this prayer.
