How to practice
Pray each day for nine consecutive days: O ever Immaculate Virgin, Mother of Mercy, health of the sick, refuge of sinners, comforter of the afflicted — you know my wants, my troubles, my sufferings. Look upon me with mercy. When you appeared in the grotto of Lourdes, you gave a mission to Saint Bernadette to pray and do penance. I beg you to obtain for me the grace I need. [State intention.] O Mary, conceived without sin, pray for us who have recourse to thee.
