Today's prayer: devotion to Mary that makes you get graces. Here's what it is

This holy devotion consists, essentially, from the revelation of the Blessed Virgin to St. Matilde, to recite every day, three Hail Marys to thank the three Persons of the Holy Trinity of power admirable privileges, Wisdom and merciful Goodness who have moved away from our divine Mother and obtain, through her intercession, the great grace of good death (final perseverance).
All must guarantee said these three Hail Marys with pity and devotion every day of his life, as far as possible, without ever losing his guilt or negligence, in order to earn every day, protecting the Queen Heaven, and therefore secure his merciful assistance. for the horrible hour of death.
These three Hail Marys can be recited several times a day, out of devotion, as some do, and also whenever the hours are listened to; but from the use introduced and recommended by the saints, especially from San Leonardo da Porto Maurizio and S. Alfonso Liguori, it is appropriate to recite the morning, on the increase, and the evening before taking rest.
Furthermore, to obtain indulgences, it is generally necessary to add some invocations. Thus we can say at the end of the Three Hail Marys: "O my Mother, beware of today's mortal sin." 1
Such was the method generally adopted by the great doctor, Sant'Alfonso Liguori, who recommended to all the faithful, both devotees and sinners, children or old people; and he wished it should never be missing, so much so that he attributed importance to the point of view of Christian life.
However, some pious and above all religious people, advised to say, after each Ave Maria "of your Immaculate Conception, or Mary, purify my body and sanctify my soul".
These two methods are equally good, free to all to adopt what has their preferences, but, in general, we recommend the first, more accessible to all and more consistent with the practice of the Three Hail Marys revealed by the Blessed Virgin to Saint Matilde.
The main thing is to piously, every day, as much as possible morning and evening, of the practice adopted.
The most favorable time to recite the Three Hail Marys is when you get up in the morning and evening. In this way, we would not be exposed to forget them.
It is still possible, provided that one is well faithful to his morning and evening prayers, to recite them immediately after this.
If, despite everything, through negligence or under the pretext of urgent work, one is tempted to omit his usual morning or evening prayer, at least that the faithful do not omit the recital of the Three Hail Mary so short, to put under the protection of the Blessed Virgin during the day and during the night.
Many good Christians and poor sinners owed their eternal salvation, one cannot doubt, to their constant fidelity to this healthy practice.
The perfection of this practice requires that the Three Hail Marys be recited on their knees, and also, if you like, "deeply inclined", as asked San Leonardo di Port-Maurice, or "face down", according to the practice recommended by S. Alfonso Liguori. However, it is sufficient to recite them on their knees, or even, if prevented, in another suitable position, even when lying down.
The essential thing, as we have said, is to recite the Holy Ave Maria with pity, in honor of the Divine Mary and to obtain her maternal protection during life and at the hour of death.
If so, this good Mother will not miss her promise.
Under his power, his wisdom and his mercy, we reach the faithful devotees of the three Hail Marys, all the necessary graces, either to be preserved from mortal sin, or to convert, make a good death and in order to go heaven .
