Let us begin on working on purifying our minds in order to practice interior mortification. To do this Saint Alphonsus says: “And above all, it is necessary to impress deeply on the mind certain fundamental spiritual maxims, such as: “God alone deserves to be loved. Sin is the only evil which we ought to hate. Whatever God wills is good. All worldly goods shall have an end. The most insignificant action, performed for God’s sake, is more profitable than the conversion of the whole world, effected from any other motive than the love of God. It is necessary to do what at the hour of death we would wish to have done. We ought to live on this earth as if there were nothing in existence but God and ourselves.” He whose mind is continually filled with holy maxims suffers little molestation from earthly objects, and is always strong enough to resist his corrupt inclinations. The Saints kept their souls always occupied with the truths of eternity, and thus in the time of temptation, were almost insensible to the goods or the evils of this life.”
