263. I have also seen writings from heaven made up of mere numbers set down in order and in a series, just as in writings made up of letters and words; and I have been taught that this writing is from the inmost heaven, and that their heavenly writing (spoken of above, n. 260, 261), when the thought from it flows down, is set forth before the angels of the lower heavens in numbers, and that this numerical writing likewise involves arcana, some of which can neither be comprehended by thought nor expressed by words. For all numbers correspond, and have a meaning, the same as words do, in accordance with the correspondence;{1} yet with the difference that in numbers generals are involved, and in words particulars; and as one general involves innumerable particulars, so more arcana are involved in numerical writing than in literal writing. From this I could see that in the Word numbers as well as words signify things. What the simple numbers signify, as 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, and what the compound numbers, as 20, 30, 50, 70, 100, 144, 1000, 10,000, 12,000, and others, may be seen in the Arcana Celestia, where they are treated of. In this writing in heaven, a number is always prefixed on which those following in a series depend as on their subject; for that number is as it were an index to the matter treated of, and from it is the determination of the numbers that follow to the particular point. {Footnote 1} All numbers in the Word signify things (n. 482, 487, 647, 648, 755, 813, 1963, 1988, 2075, 2252, 3252, 4264, 6470, 6175, 9488, 9659, 10217, 10253). Shown from heaven (n. 4495, 5265). Composite numbers have the same signification as the simple numbers from which they result by multiplication (n. 5291, 5335, 5708, 7973). The most ancient people possessed heavenly arcana expressed in numbers forming a kind of computation of states of the church (n. 575). 264. Those who know nothing about heaven, and who are unwilling to have any other idea of it than as of something purely atmospherical, in which the angels fly about as intellectual minds, having no sense of hearing or seeing, are unable to conceive that the angels have speech and writing; for they place the existence of everything real in what is material; and yet the writings in heaven have as real an existence as those in the world, and the angels there have everything that is useful for life and useful for wisdom. 265.
