5265. 'The seven good cows are seven years' means a state when truth within the interior natural is multiplied. This is clear from the meaning of 'the cows' in the good sense as the truths belonging to the interior natural, dealt with in 5198; and from the meaning of 'years' as states, dealt with in 482, 487, 488, 493, 893. There were seven because 'seven' means that which is holy and therefore adds the idea of holiness to the matter under discussion, dealt with in 395, 433, 716, 881, as well as implying a whole period from start to finish, 728. This explains why in the dream seven cows and seven heads of grain were seen, and after that why there were seven years of abundance of corn and seven years of famine. It also explains why the seventh day was made holy, why in the representative Church the seventh year was a sabbatical year, and why after seven times seven years there was a Jubilee.

[2] 'Seven' means things that are holy because of the meanings that numbers have in the world of spirits. Each number there holds some spiritual reality within it. Visual indications of numbers have appeared to me frequently, simple and compound ones, and also on one occasion a long sequence of them, when I have wondered what meanings they possessed. I have been told that they have their origin in conversations held by angels, and that it is customary from time to time to use numbers to express spiritual realities too. These numbers are not seen in heaven but in the world of spirits, where the visual presentation of such things takes place. The most ancients, who were celestial people and who talked to angels, knew all about this, which was why they used numbers to express an evaluation of the Church. The numbers used by them conveyed a general overall idea of matters for which words served to provide a detailed description. The meaning contained within every number did not however continue to be known among the descendants of these people; only the meanings of the simple numbers survived, that is to say, the meanings of two, three, six, seven, eight, twelve, and from these the meanings of twenty-four, seventy-two, and seventy-seven. In particular their descendants knew that 'seven' meant that which was most holy - that is to say, that in the highest sense 'seven' meant the Divine Himself, and in the representative sense the celestial element of love - and that the state of the celestial man was therefore meant by 'the seventh day', 84-87.

[3] It is quite evident from the numbers used plentifully in the Word that numbers mean spiritual realities, such as the following ones in John,

Let him who has intelligence reckon the number of the beast, for it is the number of a man, that is, its number is six hundred and sixty-six. Revelation 13:18.

And elsewhere in the same book,

The angel measured the wall of the holy Jerusalem, a hundred and forty-four cubits, which is the measure of a man, that is, of an angel. Revelation 11:17.

The number one hundred and forty-four is twelve squared and twice seventy-two.

5198. 'Seven cows were coming up' means the truths belonging to the natural. This is clear from the meaning of 'cows' as the truths belonging to the natural, dealt with below. The reason there were seven is that 'seven' means that which is holy, 395, 433, 716, and therefore this number contributes to any matter under consideration the idea of holiness, dealt with in 881. The matter under consideration here is likewise of a holy nature since it concerns a further rebirth of the natural through the joining of this to the celestial of the spiritual. As regards 'cows' or 'young cows' meaning the truths belonging to the natural, this becomes clear from the fact that 'bulls' and 'young bulls' mean forms of good belonging to the natural, 2180, 2566, 2781, 2830. For in the Word, when a male means good, its female means truth, and conversely when the male means truth its female means good, so that 'a cow' means some truth belonging to the natural, because 'a bull' means some form of good belonging to it.

[2] All beasts without exception that are mentioned in the Word mean affections, evil and useless beasts meaning evil affections, gentle and useful ones meaning good affections, see 45, 46, 142, 143, 246, 714, 715, 719, 776, 1823, 2179, 2180, 3218, 3519. The reason why they have such a meaning lies in the representations that occur in the world of spirits, for whenever a discussion about affections is taking place in heaven, beasts corresponding to affections of the kind under discussion are represented in the world of spirits, as I have also been allowed quite often to see. On several occasions I have wondered about the origin of that phenomenon, but have been led to perceive that the lives led by beasts are nothing else than affections; for they respond instinctively, devoid of reason, to their innate affections and are led by these to fulfill their specific functions. No other physical forms are suited to these affections devoid of reason than the kinds in which they are seen on earth. This explains why, when the discussion in heaven is about affections alone, the ultimate forms that those affections take in the world of spirits are the same in appearance as the physical forms of such beasts; for those affections cannot be clothed with any other forms than ones such as correspond to them. I have also seen beasts, the like of which do not appear anywhere at all in the natural world. They were the forms taken by affections that are not known and by affections that are mingled together.

[3] Here then is the reason why in the Word affections are meant by 'beasts', though which particular affections are meant cannot be seen from anywhere else than the internal sense. 'Bulls' means the good belonging to the natural, as may be seen in the paragraphs listed above; and as for the meaning of 'cows' as the truths belonging to the natural, this becomes clear from other places where they are referred to, such as Isaiah 11:7; Hosea 4:16; Amos 4:1, as well as from the reference in Numbers 19:2-10 to the water of separation by which they were to be made clean and which was prepared from the red cow burned to ashes outside the camp, with which cedar wood was mixed, hyssop, and twice-dyed scarlet. When the meaning of this procedure is disclosed with the help of the internal sense, it shows that 'the red cow', meaning unclean truth within the natural, is made clean by 'burning', and also by the kinds of things meant by 'cedar wood, hyssop, and twice-dyed scarlet'. The water prepared by that process represented the means of purification.
