197. This is why places and spaces in the Word (and everything that involves space) mean matters that involve state - distances, for instance, and nearness and remoteness, paths, journeys, emigrations, miles, stadia, plains, fields, gardens, cities, streets, motion, various kinds of measurement, length, breadth, height, and depth, and countless other things - for so many things that enter our thought from our world derive something from space and time.

[2] I should like only to highlight what length, breadth, and height mean in the Word. In this world we call something long and broad if it is long and broad spatially, and the same holds true for "high." In heaven, though, where thinking does not involve space, people understand length as a state of good and breadth as a state of truth, while height is their difference in regard to level (discussed above in 38). The reason these three dimensions are understood in this way is that length in heaven is from east to west, which is where people live who are in the good of love. Breadth in heaven is from south to north, where people live who are in truth because of what is good (see above, 148); and height in heaven applies to both in regard to their level. This is why qualities of this sort are meant in the Word by length and breadth and height as in Ezekiel 40-48, where the measurements are given of the new temple and the new earth, with its courts, rooms, doors, gates, windows, and surroundings, referring to the new church and the good and true things that are in it. So too all the measurements elsewhere.

[3] The New Jerusalem is similarly described in Revelation, as follows:

The city was laid out foursquare, its length the same as its breadth; and [the angel] measured the city with the reed at twelve thousand stadia; the length and breadth and height were equal. (Revelation 21:16)

Here the New Jerusalem means a new church, so its measurements mean attributes of that church, length referring to the good of its love, breadth to the truth that derives from that good, and height to both the good and the true in respect to their level. Twelve thousand stadia means everything good and true taken together. Otherwise, what would be the point of having its height be twelve thousand stadia like its length and its breadth?

We can see in David that breadth in the Word means truth:

Jehovah, you have not left me in the grasp of my enemy's hand; you have made my feet stand in a broad place. (Psalms 31:8)

I called on Jah from my constraint; he answered me in a broad place. (Psalms 118:5)

There are other passages as well; for example, Isaiah 8:8 and Habakkuk 1:6. It also holds true elsewhere.

5146. 'And in the highest basket' means the inmost degree of the will. This is clear from the meaning of 'a basket' as a degree of the will, dealt with above in 5144; and from the meaning of 'the highest' as the inmost part, dealt with in 2148, 3084, 4599. The reason 'the highest' means the inmost part is that while a person is an inhabitant of space, interior things are seen by him as higher and exterior ones as lower. But when spatial ideas are laid aside, as happens in heaven and also in a person's interior thought, the idea of height and depth is also laid aside; for height and depth belong to spatial ideas. Indeed in the inner heaven not even the idea of interior things and exterior ones exists because even that idea has a spatial element attached to it. Rather, the idea in that heaven is of a state of greater or lesser perfection; for interior things exist within a greater state of perfection than exterior ones because interior things are nearer to the Divine and exterior ones more remote from Him. This is the reason why that which is highest means that which is inmost.

[2] Nevertheless no one can have a mental grasp of the relationship of what is interior to what is exterior unless he knows about degrees, regarding which see 3691, 4154, 5114, 5145. Man has no other notion of what is interior and consequently more perfect than the ever increasing purity of something the more one breaks it down. But greater purity and greater grossness can exist simultaneously in one and the same degree, owing not only to the expanding and condensing of it but also to the limitation of it and to the introduction of similar or else dissimilar elements into it. With an idea such as that regarding his interiors man cannot possibly do other than think that exterior things are attached in a continuous manner to interior ones, and so act entirely as one with them. But if a proper idea regarding degrees is formed one may grasp how interior and exterior things are distinct and separate from one another, so distinct that interior things can come into being and remain in being without exterior ones, whereas exterior things can never do so without interior ones. One may also grasp the nature of the correspondence of interior things within exterior ones, as well as the way in which the exterior things can represent interior ones. This explains why, other than hypothetically, the learned are unable to examine the question regarding the interaction of the soul and the body. Indeed it also explains why many of them believe that life belongs intrinsically to the body, and thus that when their body dies their interiors will die too since these are closely attached to the body. But in actual fact only the exterior degree dies; the interior degree survives and goes on living.
