He forms men's tongues and eyes and ears, and imparts to them and understanding heart. With wisdom and knowledge he fills them; good and evil he shows them. He looks with favor upon their hearts, and shows them his glorious works. That they may describe the wonders of his deeds and praise his holy name. - Sirach 17:5-8
How many sins have entered into the soul through the eye as Holy Scripture indicates? - 1 John. 2:16.
Guard your eyes that they may not look upon anything contrary to purity; your ears, that they may not listen to evil conversation; your mind, by banishing from it all suggestive thoughts; your heart, by stifling impure desires at their very birth. -- St. John Baptist de la Salle
That is why they must fast by keeping them lowered and not permitting them to look upon frivolous and unlawful objects; the ears, by depriving them of listening to vain talk which serves only to fill the mind with worldly images; the tongue, in not speaking idle words and those which savor of the world or the things of the world. We ought also to cut off useless thoughts, as well as vain memories and superfluous appetites and desires of our will. In short, we ought to hold in check all those things which keep us from loving or tending to the Sovereign Good. -- St. Francis de Sales
