4635. CONCERNING THE SIRENS. It was observed that sirens are of manifold kinds; for, when they passed to their hell, some passed by beneath, some above, some through the province of the stomach, some through the province of the soles of the foot, some through other provinces; and some are imperceptible, who are above: but all those are thrust down into hell, through openings, which I have seen, below and above; and those of them, in their hell, who wished to extricate themselves thence, were thrust down more deeply. In a word, the sirens are the most pernicious of all. They make a league with various hells. They intermix in all evil, and think of nothing else than how they may obsess the interiors. They at once inject themselves thither, and first follow the thought of another, and next lead it; in this way, they take away all freedom of thinking well and truly; thus, they all take away spiritual life. Such are in immense number, at this day, from Europe.
