324. [316] In the natural kingdom in which men are whilst they live in the world, and in the spiritual kingdom where the spiritual angels are, and in the celestial kingdom in which are the celestial angels, similar things appear, so much so that there is scarcely any other difference than that the like things in the spiritual kingdom are more perfect than in the natural kingdom, and in the celestial kingdom still more perfect than in the spiritual kingdom. A spirit or an angel appears like a man in the world, even so that he knows no otherwise than that he is a man of the world. He has a similar face and a similar body, and in the face similar eyes, nostrils, ears, lips, mouth, and similar hair; and in the body also a similar breast, abdomen, loins, hands and feet, and also similar organs of generation; in a word, he is a man in external form altogether like a man of the world. He has similar lungs, because he breathes; and he has a similar heart, because it pulsates. The other interior viscera of the body are also similar, because there are societies in heaven which equally correspond to these viscera. There is likewise a ruddiness in the face, hands, arms, and body, as if from blood in the arteries and veins. There are also similar fibers, nerves, and muscles, because in like manner a spirit moves his limbs like a man in the world. Moreover, he has similar sight, hearing, smell, taste and touch. He also has similar speech and singing; he has also a similar power of imagination, thought, intellect, and will, also affection and cupidity. In a word, an angel or a spirit is so similar to a man of the world, that he himself knows no otherwise than that he is a man of the world. Conjugial love is also similar with all its effect; moreover there is not propagation, but in place of it unition of minds, and thence an increase of intelligence and wisdom. Thence it is that in the Word in its spiritual sense by marriage is meant the conjunction of truth and good, and by daughters goods, and by sons truths, and so on.
