I have also seen written materials in heaven comprising nothing but numbers arranged in a pattern and series, just like the writing of letters and words; and I have been told that these writings come from the inmost heaven, whose heavenly writing (described above in Sections 260–261) comes out as numbers for angels in the lower heavens when thought from the higher heaven flows down. I have also been told that this numerical writing enfolds mysteries, some of which cannot be grasped by thought or expressed in words. All numbers do in fact correspond and have meaning depending on their correspondence, just as words do, but with the difference that numbers represent general entities and words specific ones. Since one general entity involves countless specific ones, numeric writing enfolds more mysteries than alphabetic writing does.
I could see from this that numbers in the Word mean things just the way words do. What the simple numbers mean, like 2, 3, 4, 5, 6, 7, 8, 9. 10, and 12, and what the composite ones mean, like 20, 30, 50, 70, 100, 144, 1000, 10,000, and 12,000 and others, may be seen in Secrets of Heaven, where such matters are dealt with.
In this kind of writing in heaven the number on which the following numbers depend in sequence is always put first, as though it set their theme; for this number is a kind of title of the matter under consideration, and the numbers that follow serve to delimit the matter more specifically.
