(Retranslated into slightly more modern phrase patterns here and there, but without the slightest departure from the original text otherwise.)
It must not be thought that the powers capable of the greatest wickedness appear to us in the form of repellent familiars, and other, closely related demons. They do not. Small, visible demons are merely the effluvia which those vast forms of destructiveness have left in Their wake skin scrapings and even more tenuous shreds of evil that attach themselves to the living like leeches from some great slain leviathan of the deep that has wreaked havoc on a hundred coastal cities before plunging to its death with a thousand hurled harpoons quivering in its flesh.
For the mightiest powers there can be no death, and the hurled harpoons inflict, at most, surface injuries which heal quickly. I have said before and I shall say again until my tardily earned wisdom is accepted by my brethren as fact — in confronting that which has always been and always will be a master of magic can know only self-reproach and despair if he mistakes a temporary victory for one that he can never hope permanently to win.
