203. So far as any one is in the form of heaven he is in heaven, and is, in fact, a heaven in the least form (n. 57); consequently he is to the same extent in intelligence and wisdom; for as has been said above, all the thought of his understanding and all the affection of his will extend themselves on every side into heaven in accord with its form, and wonderfully communicate with the societies there, and these in turn with him.{1} [2] There are some who do not believe that thoughts and affections really extend themselves around about them, but believe that they are within them, because whatever they think they see within in themselves, and not as distant; but such are greatly mistaken. For as the sight of the eye has extension to remote objects, and is affected in accordance with the order of the things seen in that extension, so the interior sight, which is that of the understanding, has a like extension in the spiritual world, although not perceived by man, for the reason given above (n. 196). The only difference is that the sight of the eye is affected in a natural way, because it is affected by the things in the natural world, while the sight of the understanding is affected in a spiritual way, because by the things in the spiritual world, all of which have relation to good and truth; and man's ignorance of this is because of his not knowing that there is any light that enlightens the understanding; and yet without the light that enlightens the understanding man could not think at all (of which light see above, n. 126-132). [3] There was a certain spirit who believed that his thought was from himself, thus without any extension outside of himself and communication thereby with societies outside of him. That he might learn that this was not true his communication with neighboring societies was cut off, and in consequence, not only was he deprived of thought but he fell down as if lifeless, although tossing his arms about like a new-born infant. After a while the communication was restored to him, and then as it was gradually restored he returned into the state of his thought. [4] When other spirits had seen this they confessed that all thought and affection, and in consequence, everything of life, flow in in accordance with communication, since everything of man's life consists in his ability to think and be moved by affection, or what is the same, in his ability to understand and will.{2} {Footnote 1} Everyone in heaven has communication of life, which may be called its extension into angelic societies round about, according to the quantity and quality of his good (n. 8794, 8797). Thoughts and affections have such extension (n. 2470, 6598-6613). They are united and separated in accordance with the ruling affections (n. 4111).
