8629. A certain spirit ascending from the lower earth came to me and said that he had heard my conversation with the other spirits, but that he had understood scarcely anything that had been said about spiritual life and light. I asked him whether he wished to learn these things. He said he had not come with that intention; from which it might be inferred that he was unwilling. He was very stupid. The angels said that this man, during his life in the world, had been one of those who are celebrated for their learning. He was cold, as was plainly felt from his afflatus, which was a sign of merely natural light and of no spiritual light; thus that by means of the sciences he had not opened, but had closed for himself, the way to the light of heaven.
