"Pornographic or erotic stories and pictures are worse than filthy or polluted food. The body has defenses to rid itself of unwholesome food. With a few fatal exceptions, bad food will only make you sick but do no permanent harm. In contrast, a person who feasts upon filthy stories or pornographic or erotic pictures and literature records them in this marvelous retrieval system we call a brain. The brain won't vomit back filth. Once recorded, it will always remain subject to recall, flashing its perverted images across your mind and drawing you away from the wholesome things in life."
