Prayer of St. Gertrude the Great (for the relief of the Holy Souls in Purgatory)

Our Lord dictated the following prayer to St Gertrude the Great to release many souls from Purgatory each time it is said.

Prayer of St. Gertrude the Great.
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.

Special Note
The above prayer was given approval in 1936 by the Bishop of Liera, Portugal. This prayer is widely publicised with the claim that 1000 souls are released from Purgatory each time that it is said, however the words “1000 souls” were replaced from the original word “many” and the words “those in my own home and within my family” were added after 1936.
