63. A certain spirit ascending from the lower earth, came to me, and said that he had heard what I had been discoursing upon with' other spirits, but that he did not understand at all what was said concerning spiritual life and the light thereof. He was asked whether he was willing to be instructed concerning it. He said that he had not come with that purpose. From which I concluded that he would not comprehend such things. He was very stupid; yet it was declared by the angels, that when he lived as a man in the world, he was much celebrated for his learning. He was cold, as was manifestly felt from his breathing, which was a sign of light merely natural, and of none spiritual, thus that by the sciences he had not opened, but had closed for himself the way to the light of heaven.
