“All those who desire to advance in the love of Jesus Christ are exhorted to make a spiritual communion at least once in every visit that they pay to the Most Blessed Sacrament, and at every Mass that they hear; and it would even be better on these occasions to repeat the communions three times, that is to say, at the beginning, in the middle, and at the end. This devotion is far more profitable than some suppose, and at the same time nothing can be easier in practice.” -St. Alphonsus Liguori
