Saint Peter of Alcantara says: "Keep watch also over the senses, especially the eyes, the ears and the tongue, for through the lips is the heart scattered, and by eyes and ears is it filled with varied imaginings, and with much that disturbs the peace and repose of the soul. Hence it has been truly said that the contemplative soul should be as one deaf, blind and dumb, for the less he dissipates his energies abroad, the more will he be recollected within himself." we are all called to be contemplative souls! Saint Peter also advises: "Then, make a practice of reading spiritual and devout books. They serve to feed the imagination and to keep the heart recollected, and they lead men of good will to occupy their minds with what has appealed to them, for what the heart is full of is always the first to suggest itself to the mind. Keep the thought of God continually before you, and walk always in His presence." St. Alphonsus writes: "a single bad book will be sufficient to cause the destruction of a monastery." Pope Pius XII wrote in 1947 at the beatification of Blessed Maria Goretti: "There rises to Our lips the cry of the Saviour: 'Woe to the world because of scandals!' (Matthew 18:7). Woe to those who consciously and deliberately spread corruption-in novels, newspapers, magazines, theaters, films, in a world of immodesty!" We at St. Pius X Press are calling for a crusade of good books. We want to restore 1,000 old Catholic books to the market. We ask for your assistance and prayers. This book is a photographic reprint of the original. The original has been inspected and some imperfections may remain. At Saint Pius X Press our goal is to remain faithful to the original in both photographic reproductions and in textual reproductions that are reprinted. Photographic reproductions are given a page by page inspection, whereas textual reproductions are proofread to correct any errors in reproduction.
