In the spiritual world, or in the world where spirits and angels are, similar objects appear as in the natural world, or where men are. These are similar in that as to external appearance there is no difference. In that world appear plains and mountains, hills and rocks, and valleys between them; also waters, and many other things that are seen on earth. But yet all these things are from a spiritual origin, and all appear therefore before the eyes of spirits and angels, and not before the eyes of men, because men are in the natural world. Spiritual beings see the things that are from a spiritual origin, and natural beings the things that are from a natural origin. Consequently, man with his eyes can in no way see the objects that are in the spiritual world unless he is permitted to be in the spirit, or after death when he becomes a spirit. On the other hand, an angel and a spirit are unable to see anything at all in the natural world unless they are with a man who is permitted to speak with them. For the eyes of man are adapted to the reception of the light of the natural world, and the eyes of angels and spirits are adapted to the reception of the light of the spiritual world; although the eyes of the two are exactly alike in appearance. That the spiritual world is such, the natural man cannot comprehend, and least of all the sensual man, who believes nothing except what he sees with his bodily eyes and touches with his hands, and therefore takes in by sight and touch. He thinks from these things, so his thought is material and not spiritual. Such being the likeness between the spiritual world and the natural world, man after death can hardly believe otherwise than that he is in the world where he was born, and from which he has departed. For this reason they call death simply a translation from one world into another like it. (That the two worlds are thus alike can be seen above, where the representatives and appearances in heaven have been treated of; n. 170-176.)
