This third was taught during a vision that Sister Faustine had on the 13th

This third was taught in a vision that Sister Faustina had on September 13, 1935: "I saw an angel, the executor of the wrath of God, to the point of reaching the earth. I began to to implore God for the world with words that I heard inwardly. As I prayed this way, I saw that the angel was abandoned, and he could no longer just execute a punishment. "

The next day, an interior voice taught him this prayer in the beads of the rosary.

"By reciting this rosary, I like to give all that is asked of me. When they recite the hardened sinners, I will fill their souls with peace, and their hour of death will be happy. Write this to troubled souls: When the l soul sees and recognizes the gravity of its sins, when all the abyss of the misery in which it plunged is revealed, does not despair it, but lets launch itself with confidence in the arms of my mercy, Like a child in the arms of his dear mother. These souls have a right of precedence over my merciful heart. Say that no soul that has turned to my mercy has been disappointed or tested. "

"When they pray this rosary with the dying, I will stand between the Father and the dying soul, not as a just judge, but as a merciful Savior."

The rosary also includes the contemplation of certain passages from the life of Jesus and his mother Mary, which, according to the doctrine of the Catholic Church, are of particular importance for the history of salvation and are called "mysteries".

The rosary was traditionally divided into three equal parts, with fifty pearls each and which, because they corresponded to the third part, were called rosary.
