The Autobiography of St. Margaret Mary

 St. Margaret Mary Alacoque was born Marguerite Marie Alacoque at Lhautecour, France, in 1647. Even as a young child, she preferred prayer and silence to ordinary recreation, possessing a great love for the holy Sacrament of the Eucharist. A mystic, she also experienced visions of our Lord while still young, and took her religious habit in 1671. Subsequently, she began receiving revelations of our Lord's Sacred Heart, and published an autobiography out of obedience to her superiors. St. Margaret Mary died in 1690 and was canonized by Pope Benedict XV in 1920.
