Of all writers upon occult subjects to whose works we have as yet gained access, Paracelsus throws the greatest light upon these tricky sprites celebrated in the realm of poesy, and inhabiting that disputed land popularly termed fairydom. From open vision, and that wonderful insight of the master or adept into the secrets of nature, Paracelsus is able to give us the most positive information concerning their bodily formation, the nature of their existence, and other extraordinary particulars, which proves that he has actually seen and observed them, and doubtless also employed them as the obedient servants of his purified will; a power into which the spiritual man ascends by a species of right, when he has thrown off, or conquered, the thraldom of matter in his own body, and stands open-eyed at "the portals of his deep within."
We will quote certain extracts from the pages of this wonderful interpreter of nature. "There are two kinds of flesh. One that comes from Adam, and another that does not come from Adam. The former is gross material, visible and tangible for us; the other one is not tangible and not made from earth. If a man who is a descendant from Adam wants to pass through a wall, he will have first to make a hole through it; but a being who is not descended from Adam needs no hole nor door, but may pass through matter that appears solid to us without causing any damage to it. The beings not descended from Adam, as well as those descended from him, are organized and have substantial bodies; but there is as much difference between the substance composing their bodies as there is between matter and spirit. Yet the elementals are not spirits, because they have flesh, blood, and bones; they live and propagate offspring; they eat and talk, act and sleep, etc., and consequently they cannot be properly called spirits. They are beings occupying a place between man and spirits, resembling men and women in their organization and form, and resembling spirits in the rapidity of their locomotion. They are intermediary beings or composita, formed out of two parts joined into one; just as two colors mixed together will appear as one color, resembling neither one nor the other of the two original ones. The elementals have no higher principles; they are therefore not immortal, and when they die they perish like animals. Neither water nor fire can injure them, and they cannot be locked up in our material prisons. They are, however, subject to diseases. Their costumes, actions, forms, ways of speaking, etc., are not very unlike those of human beings; but there are a great many varieties. They have only animal intellects, and are incapable of spiritual development."
