Even if we make it to Purgatory, we will have already achieved our Salvation. But it would be ideal to avoid the pain of our purification if it was possible, we think that such possibility is only reserved to the saints, but we are about to see that God is so merciful that He has disposed of many devotions to help us to be holy and to purify our souls before we go to Heaven. Our Lady will help us also when we have a great devotion to Her, She will truly pray for us at the hour of our death and help us to minimize the purification of Purgatory.

We can avoid Purgatory living a holy life, staying away from sin, confessing our sins regularly, having the Holy Eucharist in a state of grace and practicing works of Mercy, especially having a devotion to the Holy Souls in Purgatory.

7. Whoever shall have a true devotion for the rosary shall not die without the sacraments of the Church.

6 Five Promises - Life Offering to Our Heavenly Mother

Several messages, prayers and promises were received by a Hungarian religious (Sister Dolores Elizabeth Krizsan, who died in 1998 at the age of 96), who for her humility and obedience wanted to remain unnoticed while on earth.

Our Blessed Mother implores those who have Holy Communion daily or at least once a week to offer their lives to glorify the Greatness of God and for the salvation of souls, so that the souls of sinners are not condemned but receive at least at the time of death, the Graces necessary for Salvation.

1 Their names will be written in the Hearts of Jesus and Mary, inflamed by love.
2 Their life offering, together with the infinite merits of Jesus, can save many souls from damnation. All souls who will live until the end of the world will benefit from their life offering.
3 None of their family members will go to hell, even if it seems otherwise, because they will receive, in the depths of their souls, the grace of sincere contrition before the soul departs from their bodies.
4 On the day they offer their lives, their loved ones suffering in Purgatory will be released.
5 I will be with them at the hour of their death. They will not know Purgatory. I will carry their souls straight to the presence of the Glorious Trinity, where they will live with me in a special place created by God and will rejoice forever.

7 Feast of the Divine Mercy

Concerning the Feast of the Divine Mercy Jesus said:
Whoever approaches the Fountain of Life on this day will be granted complete forgiveness of sins and punishment. (Diary 300)
On one occasion, I heard these words: My daughter, tell the whole world about My Inconceivable mercy. I desire that the Feast of Mercy be a refuge and shelter for all souls, and especially for poor sinners. On that day the very depths of My tender mercy are open. I pour out a whole ocean of graces upon those souls who approach the fount of My mercy. The soul that will go to Confession and receive Holy Communion shall obtain complete forgiveness of sins and punishment.
On that day all the divine floodgates through which grace flow are opened. Let no soul fear to draw near to Me, even though its sins be as scarlet. My mercy is so great that no mind, be it of man or of angel, will be able to fathom it throughout all eternity. Everything that exists has come forth from the very depths of My most tender mercy. Every soul in its relation to Me will contemplate My love and mercy throughout eternity. The Feast of Mercy emerged from My very depths of tenderness. It is My desire that it be solemnly celebrated on the first Sunday after Easter. Mankind will not have peace until it turns to the Fount of My Mercy. (Diary 699)
Yes, the first Sunday after Easter is the Feast of Mercy, but there must also be deeds of mercy, which are to arise out of love for Me. You are to show mercy to our neighbors always and everywhere. You must not shrink from this or try to absolve yourself from it. (Diary 742)
I want to grant complete pardon to the souls that will go to Confession and receive Holy Communion on the Feast of My mercy. (Diary 1109)

8 Rosary of the Holy Wounds   Litany
Promise 16
The soul who during life has honored the Wounds of our Lord Jesus Christ and has offered them to the Eternal Father for the Souls in Purgatory, will be accompanied at the moment of death by the Holy Virgin and the angels; and Our Lord on the Cross, all brilliant in glory, will receive her and crown her.

An indulgence is a remission before God of the temporal punishment in purgatory still due for sins after absolution, which the faithful Christian who is duly disposed gains under certain prescribed conditions through the action of the Church which, as the minister of redemption, dispenses and applies with authority the treasury of the satisfactions of Christ and the saints".
