5990. There are very many spirits at this day who desire to flow not only into man's thoughts and affections, but also into his speech and actions, thus even into the things of his body; when yet the things of the body are exempt from the particular influx of spirits and angels, and are directed by general influx. In other words, when what is thought is determined into speech, and what is willed is determined into acts, the determination and transition into the body are according to order, and are not directed by any spirits in particular; for to flow into man's bodily things is to obsess him. The spirits who will and intend this are those who in the life of the body had been adulterers, that is, who had perceived delight in adulteries and had persuaded themselves that they are allowable; and also those who had been cruel. The reason is that both the former and the latter are more corporeal and sensual than all others, and have rejected all thought about heaven, attributing all things to nature and nothing to the Divine. In this way they have closed up interior things against themselves, and have opened external things; and because in the world they had been solely in the love of these, therefore in the other life they long to return into them through man by obsessing him.
 But it is provided by the Lord that such infernals should not come into the world of spirits; they being kept in their hells, well shut up. Therefore there are no external obsessions at this day, but still there are internal ones, also the work of the infernal and diabolical crew; for evil men think such things as are filthy and also cruel towards others, and also such as are adverse and malignant toward what is Divine; and unless such thoughts were kept in check by fear of the loss of honor, of gain, and of reputation on account of these, of legal penalties, and of the loss of life, they would burst forth openly, and thus such men would rush more than the obsessed into the destruction of others, and into blasphemies against the things of faith. But these external bonds cause them not to seem to be obsessed, although they are so as to their interiors, but not as to their exteriors. This is very manifest from such as they in the other life, where external bonds are removed. There they are devils, being continually in the delight and desire of ruining others and destroying whatever is of faith.
