"The first means is the depression that one must harshly rouse in them through invective, criticism, and hatred of their thoughts and vile acts. The second means is torturing them with a strong and constant hunger. The third is tiring them greatly by means of depriving them of sleep. The fourth is throwing them into a horrible prison. The fifth is beating them frequently, until the blood flows, with whip or rod."
