if he will; then let him perfume the same with some convenient fumigation; and let him anoint his temples with some unguent efficacious hereunto, and put a ring upon his finger, of the things above spoken of: let him take either some image, or holy tables or holy paper, and place the same under his head: then having made a devout prayer, let him go unto his bed, and meditating upon that thing which he desireth to know, let him so sleep; for so shall he receive a most certain and undoubted oracle by a dream, when the Moon goeth through that signe which was in the ninth House of his nativity, and also when she goeth through the signe of the ninth House of the Revolution of his nativity; and when she is in the ninth signe from the signe of perfection. And this is the way and means whereby we may obtain all Sciences and Arts whatsoever, suddenly and perfectly, with a true Illumination of our understanding; although all inferiour familiar Spirits whatsoever do conduce to this effect; and sometimes also evil Spirits sensibly informing us Intrinsecally or Extrinsecally.
Chapter xii.
But if we would call any evil Spirit to the Circle, it first behoveth us to consider, and to know his nature, to which of the Planets it agreeth, and what. Offices are distributed to him from that Planet; which being known, let there be sought out a place fit and proper for his invocation, according to the nature of the Planet, and the quality of the Offices of the Said Spirit, as near as the same maybe done: as, if their power be over the Sea, Rivers or Flouds, then let the place be chosen in the Shore; and so of the rest. Then let there be chosen a convenient time, both for the quality of the Air, serene, clear, quiet, and fitting for the Spirits to assume bodies; as also of the quality and nature of the Planet and of the Spirit, as to wit, on his day, or the time whereas he ruleth: he may be fortunate or infortunate, sometimes of the day, and sometimes of the night, as the Stars and Spirits do require. These things being considered, let there be a Circle framed in the place elected, aswel for the defence of the Invocant, as for the confirmation of the Spirit.
