From The Glories of Mary by St. Alphonsus Liguori, a continuation of the chapter named Various Examples Appertaining to the Most Blessed Virgin Mary:
53. The brother of the King of Hungary recited every day the office of Mary. Once when he was very ill, he made a vow of chastity to the Virgin, if she would restore him to health: and he immediately recovered. But his brother having died, he was about to be married, and just as the nuptials were to be celebrated, he retired apart to recite his accustomed office. When he came to the words: Thou art fair and comely, &c. : "Quam pulchra es et decora," he saw Mary, who said to him: "If I am fair as you say, why do you leave me for another spouse? Know, that if you leave her, you shall have me for a spouse, and the kingdom of heaven instead of the kingdom of Hungary." After this the prince withdrew into a desert near Aquileia, where he lived a holy life.
54. St. John Clirnacus relates, that there was a devout religious, named Carcerio, who was accustomed often to repeat little songs in praise of Mary, and always saluted her images with a " Hail Mary." He was once afflicted with so painful a malady, that in the paroxysms of his suffering he bit his lips and tongue. He lost his speech, and was at the point of death. Whilst the religious were recommending his soul to God, the mother of God appeared to him and said: "I have come to cure thee, for I do not wish that mouth should suffer with which thou hast so often praised me. Arise, thou art healed, continue to praise me. Having said this, she sprinkled him with some drops of her milk, and immediately he was cured, and never ceased to praise her, until, visited again by his Lady at his death, he sweetly expired in her arms.
55. When St. Francis Borgia was in Rome, an ecclesiastic came to speak with him; but the saint being much occupied, sent Father Acosta to him. The ecclesiastic said to him: "Father, I am a priest and a preacher, but I live in sin, and distrust the divine mercy. After preaching a sermon one day against the obstinate, who afterwards despair of pardon, a person came to me to make his confession, who narrated to me all my sins, and at length told me that he despaired of the divine mercy. In order to do my duty, I told him that he must change his life, and trust in God; then that penitent rose to his feet and reproached me, saying: And you, who preach thus to others, why do you not amend, and why do you distrust ? Know, said he, that I am an angel come to your aid; amend and you will be pardoned. And when he had said this he disappeared. I abstained for several days from my sinful practices, but when temptation came I again returned to my sins. On another day, as I was celebrating Mass, Jesus Christ sensibly spoke to me from the host, and said: Why dost thou thus maltreat me, when I treat thee so well ? After this I resolved to amend, but at the next temptation fell again into sin. A few hours ago, a youth came to me in my apartment, and drew from under his mantle a chalice, and from this a consecrated host, saying: Do you know this Lord whom I hold in my hand ? Do you remember how many favors he has done you ? Now behold the punishment of your ingratitude, and saying this he drew a sword to kill me. I then cried: for the love of Mary do not kill me, for I will indeed amend. And then he said: This was the only thing that could save you: make a good use of this grace, for this is the last mercy for you. When he had said this he left me, and I came immediately here, praying you to receive me among you." Father Acosta consoled him, and the priest, by the advice also of St. Francis, entered another order of strict observance, where he persevered in holiness till his death.
