Further, he may be considered, (4.) as a relater of depths opened in himself, of wonders which his spirit had seen and felt in his ternario sancto. Now in this respect he is no teacher, nor his reader a learner; but all that he saith is only for the same end as St. Paul spoke of his having been in the third heaven, and hearing things not possible to be spoken in human words. And yet in these matters it is, that most of his readers, especially if they are scholars, are chiefly employed; everyone in his way trying to become masters of them. Thus, when he first appeared in English, many persons of this nation, of the greatest wit and abilities, became his readers; who, instead of entering into his one only design, which was their own regeneration from an earthly to an heavenly life, turned chemists, and set up furnaces to regenerate metals, in search of the philosopher's stone. And yet, of all men in the world, no one has so deeply, and from so true a ground, laid open the exceeding vanity of such labor, and utter impossibility of success in it from any art or skill in the use of fire. And this must with truth be affirmed of him, that there is not any possible error, that you can fall into in the use of his books, but what he gives you notice of beforehand, and warns you against it in the most solemn manner; and tells you, that the blame must be yours, if you fall into it. Neither is there any question that you can put, nor advice or direction that you can ask, but what he has over and over spoke to; telling you, in the plainest manner, what the mystery is which his books contain; how, and by whom, and for what end, they are to be read.
