Hörbuch: Practice of Perfection and Christian Virtues - First Treatise

This work is based on the material which Alphonsus Rodriguez (a Spanish Jesuit priest) collected from his spiritual exhortations to his brethren, and published at the request of his superiors. Although intended for use by his religious brethren, he modified it so it would also profit laypersons. It is a book of practical instructions on all the virtues which perfect the Christian life, whether lived in a monastery or in the world. It became popular at once, and more than 25 editions of the original Spanish have been issued, 60 editions in French, 20 in Italian, 10 in German, and 8 in Latin. This first treatise is on "Of the esteem, desire and affection we should have for what touches our spiritual progress, and of some means to aid us thereto." - Summary by Wikipedia (modified)
