Sometimes evil and black spirits approach with an abundance of stars, indeed, even displaying a whole starry sky. I had always considered this to be a sign of understanding, because stars depict the intelligent, but from these black spirits I saw, and being so instructed, realized, that stars also symbolize the insane. The difference is that when they portray the insane, they are twinkling and shifting out of their places, while when they portray understanding, they are fixed. In brightness and magnitude, the two types of stars hardly differ. 1748, 25 February.
