Prayer for the souls in purgatory is, as several saints attest, extremely effective in achieving the graces we need, because not only is the intercession of hundreds of souls on our behalf worth it, but it is also a highly rewarded practice encouraged by God. . This triduum seeks to be a brief way to ask for the help of the Purging Church for urgent or important needs that we have.
I saw the Guardian Angel who ordered me to follow him. In a moment I found myself in a misty place, filled with fire and there was a multitude of suffering souls there. These souls were praying with great fervor, but without efficacy for themselves, only we can help them. The flames that burned them, they did not touch me. My Guardian Angel did not abandon me for a single moment. I asked these souls what was their greatest torment? And they answered me unanimously that their greatest torment was longing for God. -Saint Faustina Kowalska
