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.

719. 'The beast that is not clean' means evil affections. This is clear from what has been stated and shown already about clean beasts. The clean ones are so called because they are gentle, good, and useful. Those that are not clean are the opposite - savage, evil, and useless - of which there are genera and species. These in the Word are also portrayed as wolves, bears, foxes, pigs, and many others, which mean various evil desires and malicious intentions. In the present verse it is said that unclean beasts, or evil affections, were to be taken into the ark as well, for the following reason: The character of the member of this Church is being described here, specifically by means of the ark, and thus by the things that were in or rather had been brought into the ark, that is, the things that already resided with man prior to his being regenerated. Truths and goods resided with him already, which the Lord had supplied and granted prior to his regeneration, for without truths and goods no one can possibly be regenerated. Here the evils that resided with him are referred to and are meant by 'unclean beasts' that are mentioned. While a person is being regenerated evils are present that have to be dispersed, that is, broken down and modified by means of goods. For no evil with man, that of his own doing or that which is hereditary, can ever be dispersed so far as to be banished, but remains implanted for ever. Yet it is broken down and modified by means of goods from the Lord so as to be innocuous and not seen. This is an arcanum that is still unknown. It is the evils of man's own doing that are broken down and modified, rather than those which are hereditary - something else which is not known.
