Other Recommendations
Later on, St Leonard of Port Maurice "had the three Ave Marias recited morning and evening in honor of Mary Immaculate, to obtain the grace of avoiding all mortal sins during the day or and night; moreover, he promised in a special manner eternal salvation to all those who proved constantly faithful to this practice."
Doctor of the Church St Alphonsus Liguori (1696–1787) adopted this pious practice and highly recommended it. He told parents to train their children to acquire the habit of saying three Hail Marys in the morning and evening. After each Hail Mary, he advised that the following prayer be said: "By thy pure and Immaculate Conception, O Mary, make my body pure and my soul holy."
According to the St Martha Catholic Church of the Pallottine Fathers, after Night Prayers: "Many saints have had the practice of adding three Hail Marys here in honor of Mary's purity for the grace of a chaste and holy life." Thus, it has been recommended as a daily practice for people who have received the Sacrament of Confirmation that they pray the Three Hail Marys for "purity of mind, heart and body" after examination of conscience, before going to bed.
