How by Naturall things, and their vertues we may draw forth, and attract the influencies, and vertues of Celestiall bodies.
Now if thou desirest to receive vertue from any part of the World, or from any Star, thou shalt (those things being used which belong to this Star) come under its peculiar influence, as Wood is fit to receive Flame, by reason of Sulphur, Pitch, and Oile. Nevertheless when thou dost to any one species of things, or individual, rightly apply many things, which are things of the same subject scattered amongst themselves, conformable to the same Idea, and Star, presently by this matter so opportunely fitted, a singular gift is infused by the Idea, by means of the soul of the world. I say opportunely fitted, viz. under a harmony like to the harmony, which did infuse a certain vertue into the matter. For although things have some vertues, such as we speak of, yet those vertues do so ly hid that there is seldom any effect produced by them but as in a grain of Mustard seed bruised, the sharpness which lay hid is stirred up: and as the heat of the fire doth make letters apparently seen, which before could not be read, that were writ with the juice of an Onion or milk and letters wrote upon a stone with the fat of a Goat, and altogether unperceived, when the stone is put into Vineger, appear and shew themselves. And as a blow with a stick stirs up the madness of a Dog, which before lay asleep, so doth the Celestiall harmony disclose vertues lying in the water, stirs them up, strengtheneth them, and makes them manifest, and as I may so say, produceth that into Art, which before was only in power, when things are rightly exposed to it in a Celestiall season. As for example, If thou dost desire to attract vertue from the Sun, and to seek those things that are Solary, amongst Vegetables, Plants, Metals, Stones, and Animals, these things are to be used, and taken chiefly, which in a Solary order are higher. For these are more available: So thou shalt draw a singular gift from the Sun through the beams thereof, being seasonably received together, and through the spirit of the world.
