There are spirits who, when they want to ascertain something, say that it is such, others that it is so, one after the other. And then too, while they are speaking, they watch to see whether what they are saying is flowing freely, without any slowing down or spiritual resistance, and when it is, they consider that it is true. This is a familiar phenomenon with some kinds of spirits, that is, of speaking as if they were sure, when yet it is not true, and they are not sure. Meanwhile, others [are speaking] not so positively, but observing, as said, whether any spiritual element not in agreement is present, causing the speaking not to flow. Because of this, they guess and declare, that the matter is not true. When it is flowing, then they think that it is from heaven, or from the Lord, because there is nothing there that is out of place, but all is harmonious.
