So requisite is the use of Astrology to the Arts of Divination, as it were the Key that opens the door of all their Mysteries.

It is requisite that we should here say something of Magick, which is so linked to Astrology, as being her near Kinswoman, that whoever professes Magick without Astrology, does nothing, but is altogether out of the way.

I confess that Magic teacheth many superfluous things, and curious prodigies for ostentation; leave them as empty things, yet be not ignorant of their causes. But those things which are for the profit of men -- for the turning away of evil events, for the destroying of sorceries, for the curing of diseases, for the exterminating of phantasms, for the preserving of life, honor, or fortune -- may be done without offense to God or injury to religion, because they are, as profitable, so necessary.

Every Alchymist is a Physician or a Sope-boyler.

Natural Magick is taken to be nothing else, but the chief power of all the natural Sciences; which therefore they call the top and perfection of Natural Philosophy, and which is indeed the active part of the same; which by the assistance of natural forces and faculties, through their mutual & opportune application, performs those things that are above Human Reason.

All these delusions of Divination have their root and foundation from Astrology. For whether the lineaments of the body, countenance, or hand be inspected, whether dream or vision be seen, whether marking of entrails or mad inspiration be consulted, there must be a Celestial Figure first erected, by the means of whole indications, together with the conjectures of Signs and Similitudes, they endeavour to find out the truth of what is desired.
