3978. CONCERNING THE MOST DECEITFUL. There were some who, when I suddenly awoke in the middle of the night, assaulted me with such a subtlety of deceit as cannot be described. It was scarcely observed by the angelic spirits, but I suddenly became aware of it. It was afterwards said to me that such obtain entrance, by special permission, among angelic spirits, who are scarcely able to observe them except from the effects produced. They that are such esteem adulteries of no account, although the fact can scarce be detected so adroit are they in concealment; their power in this respect baffling even the angelic spirits. - 1748, November 17.
