45. They were also questioned about the sun of the system, how it appears from their earth. They said that it appeared large, and larger there than from other earths; they said that they knew this from the ideas of other spirits respecting the sun. They said further that they enjoyed a middle temperature, neither too hot nor too cold. It was then given me to tell them, that it has been so provided for them by the Lord, in order that they might not be exposed to excessive heat from the circumstance of their earth being in greater proximity to the sun than the other earths, since heat does not arise from nearness to the sun, but from the height and density of the aerial atmosphere, as is evident from the cold on high mountains even in hot climates; also, that heat is varied according to the direct or oblique incidence of the sun's rays, as is evident from the seasons of winter and summer in every region. These are the particulars which it has been given me to know respecting the spirits and inhabitants of the earth Mercury. THE EARTH OR PLANET JUPITER, AND ITS SPIRITS AND INHABITANTS. 46. It has been given me to have longer intercourse with the spirits and angels of the planet Jupiter than with the spirits and angels from the other planets; and I can therefore relate more particulars respecting their state of life and respecting that of the inhabitants of that planet. That those spirits were from that planet, was evident from many circumstances, and was also declared from heaven. 47. The earth or planet Jupiter itself does not indeed appear to spirits and angels: for in the spiritual world no earth is ever visible to any one, but only the spirits and angels who are from it. Those who are from the planet Jupiter appear in front to the left, at some little distance, and this constantly (see above, no. 42): there also the planet is. The spirits of every earth are near their own earth, because they are from its inhabitants (for every man after death becomes a spirit), and because they are thus of a similar genius, and can be with the inhabitants and be of service to them. 48. They related that in the region of their earth where they had lived when in the world, the multitude of human beings was as great as the earth could support; that it was fertile, and abounded in all things; that the inhabitants desired no more than sufficed for the necessities of life, and that what was not necessary they did not regard as useful; and that therefore the multitude of human beings was so great. They said that their principal care was the education of their children, and that they loved them most tenderly.
