When he has seen, that it is not his, nor any man's, but it is the soul which made the world, and that it is all accessible to him, he will know that he, as its minister, may rightfully hold all things subordinate and answerable to it.
It's prudent to gain the whole world and lose your own soul. But don't forget that your soul sticks to you if you stick to it; but the world has a way of slipping through your fingers.
The cure of the part should not be attempted without treatment of the whole. No attempt should be made to cure the body without the soul. Let no one persuade you to cure the head until he has first given you his soul to be cured, for this is the great error of our day, that physicians first separate the soul from the body.
If I cannot retain my moral influence over a man except by occasionally knocking him down, if that is the only basis upon which he will respect me, then for the sake of his soul I have got occasionally to knock him down.
