Veronica of Milan

She was reputed to have received frequent visions of the Virgin Mary, and her local cultus was confirmed by Pope Leo X in 1517.

[1] Her parents set their daughter on the path to Christian virtues, as it was said that her father was a scrupulously honest man, never selling a horse without first disclosing its faults or imperfections to the buyer.

[2] As she developed a desire for saintliness and perfection, she became tired of the joking and songs of her companions, even hiding her head and weeping as she worked.

[3] Instead, the Virgin taught her in the form of three mystical letters: The first signified purity of intention; the second, abhorrence of murmuring or criticism; the third, daily meditation on the Passion.

By the first she learned to begin her daily duties for no human motive, but for God alone; by the second, to carry out what she had thus begun by attending to her own affairs, never judging her neighbor, but praying for those who manifestly erred; by the third she was enabled to forget her own pains and sorrows in those of her Lord, and to weep hourly, but silently, over the memory of His wrongs.Veronica became accustomed to nearly constant apparitions and religious ecstasies.
