Purgatory is not a walk in the park, it is a place of great suffering as we know from many of the Saints of the Church who have seen it or have had souls from Purgatory visiting them. They are in great need of our Prayers and most especially we should have Masses said for them.
Here below is an excerpt from St. Faustina's diary on her experience of Purgatory...
"One day I asked the Lord, ‘Lord, who else should I pray for?’ Jesus said that on the following night He would let me know for whom I should always pray for.
The following night, I saw my Guardian Angel who asked me to follow him. In a moment I was in a misty place full of fire in which there was a great crowd of suffering souls. They were praying fervently, but to no avail, for themselves; only we can come to their aid. The flames which were burning them did not touch me at all. My Guardian Angel did not leave me for an instant. I asked these souls what their greatest suffering was. They answered me in one voice that their greatest torment was longing for God. I saw Our Lady visiting the souls in Purgatory. The souls call her ‘The Star of the Sea.’ She brings them refreshment. I wanted to talk with them some more, but my Guardian Angel beckoned me to leave. We went out of the prison of suffering. [I heard an interior voice] which said, My mercy does not want this, but justice demands it. Since that time, I am in closer communion with the suffering souls."
Diary No. 58
"One night, a sister who had died two months previously came to me. She was a sister of the first choir. I saw her in a terrible condition, all in flames with her face painfully distorted. This lasted only a short time, and then she disappeared. A shudder went through my soul because I did not know whether she was suffering in purgatory or in hell. Nevertheless, I redoubled my prayers for her. The next night she came again, but I saw her in an even more horrible state, in the midst of flames which were even more intense, and despair was written all over her face. I was astonished to see her in a worse condition after the prayers I had offered for her, and I asked, ‘Haven’t my prayers helped you?’ She answered that my prayers had not helped her and that nothing would help her. I said to her, ‘And the prayers which the whole community has offered for you, have they not been any help to you?’ She said no, that these prayers have helped some other souls. I replied, ‘If my prayers are not helping you, Sister, please stop coming to me.’ She disappeared at once. Despite this, I kept on praying.
"After some time she came back again to me during the night, but already her appearance had changed. There were no longer any flames, as there had been before, and her face was radiant, her eyes beaming with joy. She told me that I had a true love for my neighbor and that many other souls had profited from my prayers. She urged me not to cease praying for the souls in purgatory, and she added that she herself would not remain there much longer. How astounding are the decrees of God!"
Saint Peter Damien tells that his sister remained several years in Purgatory because she had listened to an evil song with some little pleasure. It is told that two religious promised each other that the first to die would come to tell the survivor in what state he was. God permitted the one who died first to appear to his friend. He told him that he was remaining fifteen years in Purgatory for having liked to have his own way too much. And as his friend was complimenting him on remaining there for so short a time, the dead man replied: "I would have much preferred to be flayed alive for ten thousand years continuously, for that suffering could not even be compared with what I am suffering in the flames." A priest told one of his friends that God had condemned him to remain in Purgatory for several months for having held back the execution of a will designed for the doing of good works. Alas, my dear brethren, how many among those who hear me have a similar fault with which to reproach themselves?
Prayer of St. Gertrude - Eternal Father, I offer you the Most Precious Blood of your Divine Son Jesus, in union with the Masses said throughout the world today, for all the Holy Souls in Purgatory, for sinners everywhere, for those in my own home and in my own family. Amen
