160. I afterwards conversed with those spirits concerning their earth; for all spirits can do this when their natural or external memory is opened by the Lord; for this they carry with them from the world, but it is not opened except at the Lord's good pleasure. Respecting their earth, from which they had come, the spirits then said that when leave is given them, they appear to the inhabitants, and converse with them, as men; and that this is effected by their being let into their natural or external memory, and consequently into such a thought as they had been in when they lived in the world; and that on such occasions the inhabitants have their interior sight or the sight of their spirit opened, by which they see the spirits. They added, that the inhabitants know no otherwise than that they are men of their earth, and only apperceive they are not when they are suddenly removed from their sight, I told them that the same thing also happened on our Earth in ancient times, as, for instance, to Abraham, Sarah, Lot, the inhabitants of Sodom, Manoah and his wife, Joshua, Mary, Elizabeth, and the prophets generally; and that the Lord appeared in like manner, and they who saw Him knew no otherwise than that He was a man of the earth, till He revealed Himself. But that at the present day this rarely happens; the reason is, lest men by such things should be compelled to believe; for compelled faith, such as is the faith which enters by means of miracles, does not inhere, and would also be hurtful to those with whom faith may be implanted by means of the Word in a state without compulsion. 161. The spirit, who had been a prelate and a preacher in the world, entirely disbelieved that any other earths existed besides our own, because he had thought in the world that the Lord was born on this Earth alone, and that without the Lord none could be saved; wherefore he was reduced into a state similar to that into which spirits are reduced when they appear on their own earth as men (which state has been treated of just above); and thus he was let into that earth, so that he not only saw it, but also conversed with the inhabitants there. This done, a communication was by this means granted me also, so that I likewise saw the inhabitants, and also some objects on that earth (see above, no. 135). There appeared then four kinds of men, but one after the other in succession; the first I saw were clothed; the second were naked, of a human flesh colour; the next were naked, but with flame-coloured bodies; and the last were black.
