This can always comfort me and keep me secure: my mind, which rules over everything, will not bring trouble on itself. It will not put itself in fear. It will not lead itself into harmful desires. If someone else has the power to make it fear or grieve, then let them use that power. But if my mind does not incline itself toward such feelings through some false belief, then there is nothing to fear. As for the body, why should I make the pain of my body into the pain of my mind? If the body can fear or complain, let it.
This may ever be my comfort and security: my understanding, that ruleth over all, will not of itself bring trouble and vexation upon itself. This I say; it will not put itself in any fear, it will not lead itself into any concupiscence. If it be in the power of any other to compel it to fear, or to grieve, it is free for him to use his power. But sure if itself do not of itself, through some false opinion or supposition incline itself to any such disposition; there is no fear. For as for the body, why should I make the grief of my body, to be the grief of my mind? If that itself can either fear or complain, let it.
