Prayer to avoid Purgatory at the end of our life

A poor deceased Clarissa appeared to her Superior who prayed for her and said:
"I went straight to Heaven because, having recited this prayer every evening, I paid all my debts and was preserved from Purgatory".

Eternal Father, through the hands of Mary of Sorrows, I offer you the Sacred Heart of Jesus with all His love, with all His sufferings and with all His merits:
.
to atone for all the sins I have committed today and throughout my past life;
Glory to the Father ...
to purify the good that I have done badly today and throughout my past life;
Glory to the Father ...
to make up for the good I have neglected to do today and throughout my past life.
Glory to the Father ...
