429. The world of spirits appears like a valley between mountains and rocks, with windings and elevations here and there. The gates and doors of the heavenly societies are visible to those only who are prepared for heaven; others cannot find them. There is one entrance from the world of spirits to each heavenly society, opening through a single path which branches out in its ascent into several. The gates and doors of the hells also are visible only to those who are about to enter, to whom they are then opened. When these are opened gloomy and seemingly sooty caverns are seen tending obliquely downwards to the abyss, where again there are many doors. Through these caverns nauseous and fetid stenches exhale, which good spirits flee from because they abominate them, but evil spirits seek for them because they delight in them. For as everyone in the world has been delighted with his own evil, so after death he is delighted with the stench to which his evil corresponds. In this respect the evil may be likened to rapacious birds and beasts, like ravens, wolves, and swine, which fly or run to carrion or dunghills when they scent their stench. I heard a certain spirit crying out loudly as if from inward torture when struck by a breath flowing forth from heaven; but he became tranquil and glad as soon as a breath flowing forth from hell reached him. 430. With every man there are two gates; one that leads to hell and that is open to evils and their falsities; while the other leads to heaven and is open to goods and their truths. Those that are in evil and its falsity have the gate to hell opened in them, and only through chinks from above does something of light from heaven flow into them, and by that inflowing they are able to think, to reason, and to speak; but the gate to heaven is opened in those that are in good and its truth. For there are two ways that lead to the rational mind of man; a higher or internal way through which good and truth from the Lord enter, and a lower or external way through which evil and falsity enter from hell. The rational mind itself is at the middle point to which the ways tend. Consequently, so far as light from heaven is admitted man is rational; but so far as it is not admitted he is not rational, however rational he may seem to himself to be. This has been said to make known the nature of the correspondence of man with heaven and with hell. While man's rational mind is being formed it corresponds to the world of spirits, what is above it corresponding to heaven and what is below to hell. With those preparing for heaven the regions above the rational mind are opened, but those below are closed to the influx of evil and falsity; while with those preparing for hell the parts below it are opened, and the parts above it are closed to the influx of good and truth. Thus the latter can look only to what is below themselves, that is, to hell; while the former can look only to what is above themselves, that is, to heaven.
