By actual experience I learned that evil spirits from the devil's gang can also enter into heaven and be among those who are there and, as they believe, can do this by means of tricks that they think up - something I was also granted to hear. For they thought that I did not understand their intrigues, but I was enabled to hear and see them. Their plotting was about a way by which they imagined they could safely enter. One method they turned down, another they seemed to themselves to discover, by which, in fact, they did ascend. This I perceived also by sense; but as I had been taught previously [307, 314], they are then surrounded by a spiritual field, which makes them unable to tell otherwise than that they are now in heavenly joy, because of being in heaven. But these are cases of permission, and the angels of that heaven are not aware at the time that such spirits are there. But if any one of those spirits were deprived of the spiritual field adapted to each one's state of mind - and also changing at every moment - then the angels even from very far off would not be able to bear their approach, much less that they should enter, because it causes such coldness that they could never be together. This coldness it was also granted me to be conscious of and to feel plainly. 1747, the l8th day of December.
