Of Spirits in General; What they are and how to be considered: Also how farr the Power of Magitians and Witches is able to operate in Diabolical Magick.
1.
Ecause The reason of this Addition.the Author in his foregoing Treatise, upon the Nature of Spirits and Devils, hath only touched the subject thereof superficially, omitting the more material part; and with a brief and cursory Tractat, hath concluded to speak the least of this subject which indeed requires most amply to be illustrated; therefore I thought fit to adjoyn this subsequent discourse; as succedaneous to the fore-going, and conducing to the compleating of the whole work.
The nature of Spirits.2. The Nature of Spirits is variously to be considered, according to the source to which each Caterva doth belong: for as some are altogether of a divine and celestial nature; not subject to the abominable Inchantments and Conjurations of vitious mankind; so others are the grand Instigators, stirring up mans heart to attempt the enquiry after the darkest, and most mysterious part of Magick, or Witchcraft: neither is this their suggestion without its secret end: that is, that by the private insinuation, and as it were incorporating themselves into the affection, or desire of the Witch, or Magician; they may totally convert him into their own nature: reducing him at last by constant practice, to such obdurateness and hardness of heart, that he becometh one with them, and delighted with their association, being altogether dead to any motions in himself that may be called good.
3. And if we may credit example, which is the surest proof; the very The original of evil essences. imaginations, and affection of a Magician, doth create an evil Essence or Devil; which was not before in being: for, as the Astral Spirits are believed by many to Germinate and procreate one another, so likewise are the infernal Spirits capable of multiplication in their power and essence, according to their Orders, Ranks and Thrones; by means of the strong imagination in a Witch, or malevolous person, earnestly desiring their assistance.
