5715. There once appeared a great quadrangular opening that extended obliquely downward to a considerable depth. In the deep was seen a round opening, which was then open but presently was closed. From it exhaled a dangerous heat, collected from various hells, and arising from cupidities of various kinds, as from arrogance, lewdness, adultery, hatred, revenge, quarrels, and fights, from which arise in the hells such heat as exhaled. When it acted upon my body it instantly brought on disease like that of a burning fever; but when it ceased to flow in, this effect of disease at once ceased. When a man falls into such a disease as he has contracted from his life, then forthwith an unclean sphere corresponding to the disease attaches itself, and is present as a fomenting cause. That I might know for certain that this is the case, there have been spirits with me from a number of hells, through whom the sphere of exhalations thence was communicated; and according as it was permitted to act upon the solid parts of the body, I was seized with oppression, with pain, even with the corresponding disease, which ceased in an instant when those spirits were driven away; and that no room for doubt might be left, this has been done a thousand times.
