4. -II-. The spiritual world first existed and continually subsists from its own sun; and the natural world from its own sun.

That there is one sun of the spiritual world and another of the natural world is because those worlds are altogether distinct from each other, and a world derives its origin from a sun. For a world in which all things are spiritual cannot originate from a sun, all the products of which are natural, since thus there would be physical influx, which, however, is contrary to order. That the world came into existence from the sun, and not the sun from the world, is evident from the consequence of the fact that the world, as to all things belonging to it, in general and in particular, subsists by means of the sun; and subsistence proves existence, hence it is said that subsistence is perpetual existence: thus it is evident that if the sun were removed its world would fall into chaos, and this chaos into nothing.

[2] That in the spiritual world there is a sun different from that in the natural world I am able to testify, for I have seen it: in appearance it is fiery, like our sun, of nearly the same magnitude, and at a distance from the angels as our sun is from men. It does not rise or set, however, but stands immovable in a middle altitude between the zenith and the horizon, whence the angels enjoy perpetual light and perpetual spring.

[3] A man given to reasoning, who knows nothing concerning the sun of the spiritual world, easily becomes insane in his idea of the creation of the universe. When he deeply considers it, he perceives no otherwise than that it is from nature; and because the origin of nature is the sun, that it is from its sun as a creator. Moreover, no one can have a perception of spiritual influx, unless he also knows its origin: for all influx proceeds from a sun; spiritual influx from its sun, and natural influx from its sun. The internal sight of a man, which is the sight of his mind, receives influx from the spiritual sun; but the external sight, which is that of the body, receives influx from the natural sun, and in operation they unite, just as the soul does with the body.

[4] Hence it is evident into what blindness, darkness, and stupidity those may fall who know nothing of the spiritual world and its sun; into blindness, because the mind, depending solely upon the sight of the eye, becomes in its reasonings like a bat, which flies by night in a wandering course, and sometimes into linen clothes which may be hanging up; into darkness, because the sight of the mind, when the sight of the eye is flowing into it from within, is deprived of all spiritual light [lumen], and becomes like that of an owl; into stupidity, because the man still thinks, but from natural things about spiritual, and not the other way round; consequently, idiotically, foolishly, and insanely.

9. VII. The sun of the natural world is pure fire; and the world of nature first existed and continually subsists by means of this sun

That nature and its world — by which we mean the atmospheres and the earths which are called planets, among which is the terraqueous globe on which we dwell, together with all the productions, in general and in particular, which annually adorn its surface subsist solely from the sun, which constitutes their centre, and which, by the rays of its light and the modifications of its heat, is everywhere present, everyone knows for certain, from his own experience, from the testimony of the senses, and from the writings which treat of the way in which the world has been peopled. As, therefore, perpetual subsistence is from this source, reason may also conclude with certainty that existence is likewise from the same; for perpetually to subsist is perpetually to exist as a thing first existed. Hence it follows that the natural world was created by Jehovah God by means of this sun as a secondary cause.

[2] That there are spiritual things and natural things, entirely distinct from each other, and that the origin and support of spiritual things are from a sun which is pure love, in the midst of which is Jehovah God, the Creator and Upholder of the universe, has been demonstrated before; but that the origin and support of natural things are a sun which is pure fire, and that the latter is derived from the former, and both from God, follows of itself, as what is posterior follows from what is prior, and what is prior from The First.

[3] That the sun of nature and its worlds is pure fire, all its effects demonstrate: as the concentration of its rays into a focus by the art of optics, from which proceeds violently burning fire and also flame; the nature of its heat, which is similar to heat from elementary fire; the graduation of that heat according to its angle of incidence, whence proceed the varieties of climate, and also the four seasons of the year; besides many other facts, from which the rational faculty, by means of the senses of the body, may confirm the truth that the sun of the natural world is mere fire, and also that it is fire in its utmost purity.

[4] Those who know nothing concerning the origin of spiritual things from their own sun, but are only acquainted with the origin of natural things from theirs, can scarcely avoid confounding spiritual and natural things together, and concluding, through the fallacies of the senses and of the rational faculty derived from them, that spiritual things are nothing but pure natural things, and that from the activity of these latter, excited by heat and light, arise wisdom and love. These persons, since they see nothing else with their eyes, and smell nothing else with their nostrils, and breathe nothing else through their lungs but nature, ascribe to it all things rational also; and thus they imbibe what is natural as a sponge sucks up water. Such persons may be compared to charioteers who yoke the team of horses behind the carriage, and not before it.

[5] The case is otherwise with those who distinguish between things spiritual and natural, and deduce the latter from the former. These also perceive the influx of the soul into the body; they perceive that it is spiritual, and that natural things, which are those of the body, serve the soul for vehicles and mediums, by which to produce its effects in the natural world. If you conclude otherwise you may be likened to a crayfish, which assists its progress in walking with its tail, and draws its eyes backward at every step; and your rational sight may be compared to the sight of the eyes of Argus in the back of his head, when those in his forehead were asleep. Such persons also believe themselves to be Arguses in reasoning; for they say, 'Who does not see that the origin of the universe is from nature? And what then is God but the inmost extension of nature?' and make similar irrational observations, of which they boast more than wise men do of their rational sentiments.
