Instruments of the heavens

An instrument is that with which the active agent is active and the passive patient is passive, as when a blacksmith uses a hammer to actively work on iron; and like the fire in a furnace prepared by a blacksmith to soften the iron. And the same with the intellect, as man uses it to understand things, and the sense of taste to taste things and so forth. And therefore astronomers say that the instruments above are the acts and operations of the signs and planets and that A B C D act as their instruments for influencing things below.

Heat is an instrument of fire and the act of heating is an instrument of heat: like the blacksmith's hand used as a working instrument and like a hammer striking a nail used as an instrument by both the nail and the hand. And therefore astronomers say that instruments above have a dual character and cause dual instances of instruments in things below in accordance with natural instinct and appetite.

The instruments of heaven exist so that natural instruments can exist below and so that the natural instruments can be used to invent the artificial instruments that are necessary to life, like human eyes are instrument for seeing and teeth are for eating and there are other such natural instruments like the leaves of a tree that serve to protect flowers and fruit, and the wings of a bird used for flight and like a blacksmith's hammer used for pounding out iron, and the same with other instruments that humans and nature require , all of which are finally meant for man. The instruments of heaven also exist to ensure that instruments below are applied and used to serve human life and the life of other animals, plants and natural entities.

Heaven has many instruments, as many as required for causing the numerical multiplication and real quantity of substances below, for instance: the Sun has an instrument as great as it needs for producing daylight, and Aries, Taurus and Gemini have instruments large enough to enable them to produce the spring season. And likewise with other similar things.

With their proper qualities, the instruments of heaven cause the proper qualities of things below, like Aries using its goodness to cause the goodness of fire and its greatness to cause greatness in fire and its natural heat to intensify the heat of fire and its natural dryness to intensify the dryness in fire; and Aries uses fire to cause the generation of elemented bodies of the fiery complexion; and people born under Aries are of a fiery complexion, and so forth.

Time is an instrument of the heavenly bodies for causing time to proceed in things below, like Leo and Mars that cause summertime, and so on. And the heavenly loci and modes are the instruments that cause the disposition of loci and modes below, like the loci of sign and planet combinations used by astronomers to make judgment; and like the modes of heaven used as instruments to make informed judgments about the functions that exist in things below.

Having dealt with the nine general questions with which the secrets of nature and of astronomy can be investigated, let us now use them to inquire into the soul of heaven.
