There were quite a few spirits around me who were not good. An angel came, and I saw that the spirits could not bear his presence, since the nearer he came, the farther away they went. I was surprised but was able to see that they could not linger in the aura that he carried with him. This too showed me, as other experiences have done, that one angel can drive away tens of thousands of evil spirits, since evil spirits cannot abide an atmosphere of mutual love.
Still, I could tell that his aura was being moderated by his associations with others. If it had not been, all the spirits would immediately have scattered.
This once again shows clearly what kind of perception exists in the other life, and it shows how people join together and separate in response to their perceptions.
All spirits have contact with the inner heaven and the inmost (although they are unaware of it); otherwise they could not live. Their inner nature is recognized by angels, who are awake to deeper dimensions, and the Lord also governs them through angels. So their inner characteristics become common knowledge in heaven, as their outer ones do in the world of spirits.
These inner communications adapt each of them for some useful role, and they are drawn to that role without realizing it.
The situation with people on earth is the same. We too communicate through angels with heaven—in complete ignorance of the fact that we do—because otherwise we could not live. (The influence heaven has on our thinking is merely the outermost effect of that interaction.) Such contact is the source of all our life, and it regulates everything we try to do in life.
