171. There is no way to describe briefly how things look to angels in the heavens. To a considerable extent, they look like the things we see on earth, but they are more perfect in form and also more abundant.

We may conclude that there are things like this in the heavens because of what the prophets saw - for example what Ezekiel saw of the new temple and the new earth as described in chapters 40-48 [of his book], what Daniel describes in his chapters 7-12, what John saw as described from the first through the last chapter of Revelation, along with other visions presented in both the historical and the prophetic books of the Word. They saw things like this when heaven was opened to them, and heaven is said to be opened when our inner sight, the sight of our spirit, is opened. For the things that exist in heaven cannot be seen with our physical eyes, but only with the eyes of our spirit; and when it pleases the Lord, these are opened. At such times we are led out of the natural light that our physical senses are in and raised into the spiritual light in which we dwell because of our spirit. This is the light in which I have seen the things that exist in the heavens.

2733. There were certain spirits who, from a practice followed by them during their lifetime, were molesting me with particular skill. They did so by means of a rather gentle wave-like influx, resembling the ordinary influx from upright spirits. But I perceived that within that influx trickery and the like were present, to entice and to deceive. At length I spoke to one of them who, I was told, had during his lifetime been the commander of an army. And because I perceived that licentiousness was present in the ideas comprising his thought, I talked to him about marriage in the language used by spirits, which is illustrated with representatives and which expresses one's sentiments completely and many things in an instant.

[2] He said that during his lifetime he had thought nothing of adulterous behaviour. But I was given to tell him that all adultery is quite unspeakable, even though to those who are guilty of it it does not seem - because of the delight they take in it and the persuasive beliefs that result from it - to be unspeakable, but even allowable. I said that he might also know this from the fact that marriages are the seminaries of the human race and therefore the seminaries of the heavenly kingdom as well, and for that reason must not on any account be violated but be held sacred. He might also know, I continued, that adultery is unspeakable from the fact, which he ought to know because he was now in the next life and in a state of perception, that conjugial love comes down from the Lord by way of heaven, and that from that love, as from a parent, mutual love is derived, which is the foundation on which heaven rests. And he might know it also from the fact that when they merely move towards heavenly communities adulterers become aware of their own stench and cast themselves away from there down towards hell. He might at least have known that violence done to marriages was contrary to Divine laws, and contrary to the civil laws of all people, as well as contrary to the genuine light of reason, since it is contrary to order, both Divine and human, not to mention many considerations besides these.

[3] But he replied that he had never known such things during his lifetime, nor had he thought about them. He wished to reason whether what he had heard was so, but he was told that in the next life truth leaves no room for reasonings, for reasonings lend support to a person's delights, and so to his evils and falsities. I went on to tell him that he ought first to think about the things he had been told, because they were true; or at least he ought to think from the principle very widely known in the world that nobody ought to do to another what he does not wish that other to do to him. If some other man, I asked, had in a similar way seduced the wife whom he loved - as men love their wives at the beginning of every marriage - would he not also, when feeling irate about what had occurred, have expressed, if he spoke from that feeling, a loathing for all adultery? Also, being a man with mental ability, would he not have confirmed himself more than others against all adultery, even condemning it to hell? Thus he might have judged himself from what he possessed within himself.
