5.  There are times when we must use violence and courageously resist our sensual appetite, having no regard for the likes and dislikes of the flesh; but rather, making sure that the body, despite its protests, becomes subject to the spirit.
   It must be chastised and compelled to serve, until it is ready to obey in all things what the soul commands, and until it learns to be content with little, to delight in simple things and not to complain at any inconvenience.
