Not Sleep, not Rest, not Contentment are of the Will of the Hero, but these Things he hateth, and consenteth to enjoy them only with Same of his weak Nature. But he will analyse himself without Pity, and he will do all Things soever that may free and fortify his Mind and Will. Know that the Technick of the Right Use of this Magick with Poisons is subtle; and since the Nature of every Man differeth from that of his Fellow, there entereth Idiosyncrasy, and thine Experience shall be thy Master in this Art. Heed also this Word following: The Right Use of these Agents is to gain a Knowledge preliminary of thine own Powers, and of High States, so that thou goest not altogether blindly and without Aim in thy Quest, ignorant of the Ways of thine own inner Being. Also, thou must work always for a definite End, never for Pleasure or for Relaxation, except thou wilt, as a good Knight is sworn to do. And thou being Hero and Magician art in Peril of abusing the fiery Agents only, not those of Earth, Air or Water; because these do really work with thee in Purity, making thee wholly what thou wouldst be, an Engine indefatigable, a Mind clear, calm, and concentrated, and a Heart fierce aglow.
