Behold this is the difference with the spirits, especially of this Earth planet, as a consequence of discarding the flesh. Something similar but much rarer, can also happen to the inhabitants of Jupiter and still more rarely with the inhabitants of the planets Saturn, Uranus and the third, still undiscovered planet. But none of the spirits of the inhabitants of the latter planets immediately get to the highest heaven, but only to the first, the wisdom heaven. – The Natural Sun, Chapter 3, Paragraph 17
