6400. 'Biting the horse's heels' means false notions received from the lowest natural level. This is clear from the meaning of 'biting' as clinging to and thereby causing harm, and from the meaning of 'the horse's heels' as false notions received from the lowest natural level; for 'the heel' is the lowest and bodily part of the natural, 259, 4938-4952. While 'horse' is the understanding part of the mind, 2761, 2762, 3217, 5321, 6125. 'Horse' here means false notions because the lowest natural level of the understanding, which is that of the senses, is meant. People who are guided by truth but not as yet by good are subject to false notions received from that lowest natural level. This may be recognized from the consideration that truth is not in any light unless good resides with it or exists within it. For good is like a flame radiating light, and when that good meets some truth it not only throws light on it but also draws it into that radiating light, towards itself. People therefore who are guided by truth but not as yet by good are in a kind of gloom and darkness, because truth possesses no light at all of its own, and the light which those people receive from good is as feeble as light which fades away. When such people therefore think and engage in reasoning about truth, and from truth about good, they are like those who see apparitions in the darkness and believe them to be real bodies. Or they are like people who in the gloom see streaks on a wall and whose imagination leads them to make some shape out of them, either of a human being or of some other living creature. But when daylight comes it is seen that they are merely streaks without any such shape. It is much the same with the truths residing with them; for they see as truths what are not truths, which ought rather to be likened to apparitions or streaks on the wall. What is more, people of this kind - those who have been guided by some truth from the Word but not by any good - have been the source of all the heresies that have arisen within the Church; for heretical belief has been seen by them to be altogether the truth. So too with falsities within the Church. Those who have disseminated them have not been guided by good, as may be recognized from the consideration that they cast the good of charity far behind the truth of faith and as a consequence have for the most part invented ideas which are in no way compatible with the good of charity.

[2] Since it is said that those who are guided by truth but not as yet by good use false notions received from the lowest natural level to reason about truth and about good, let something also be said about what false notions are. Take for example a person's life after death. People subject to false notions received from lowest nature, such as those who are guided by truth but not as yet by good, do not believe that any part of a person except his body has life, or that a person can possibly rise again when he dies unless he gets back his body. If these people are told that the interior man is the one who has life within the body and who is raised up by the Lord when the body dies, and that this interior man has a body like those that spirits or angels have, and that like a person in the world he can see, hear, talk, mix with others, and seem to himself to be altogether a person, they cannot grasp any of it. False notions received from the lowest natural level cause them to believe that such things cannot be true.

[3] The chief reason why they do not believe them to be true is that they cannot see those things with their physical eyes. When such people think about the spirit or soul, the only idea they can have of it is that it is like things the eye cannot see in the natural world. Consequently they consider it to be either something breath-like, or else something air-like, ether-like, or flame-like, or - according to some - something purely thought-like, which possesses scarcely any vitality until it is joined again to the body. These people think the way they do because to them everything of an interior nature is gloom and darkness and only those of an external nature are in light. This shows how easily such people can fall into error; for if they limit their thought to the body and how it will be reassembled, to the destruction of the world and the fact that it has been awaited in vain for so many centuries, to animals and the fact that they have life not unlike man's life, or to the fact that no dead persons reappear and declare their state of life, they easily recede - when they think of these and other such things - from belief in resurrection, as they do from many other matters of belief. The reason they recede from that belief is that they are not guided by good and do not through good see in the light. Such being their condition it also says, 'And its rider will fall backwards; I wait for Your salvation, O Jehovah', meaning a receding from [the truth] unless the Lord comes to their aid.

2762. The origin of 'a horse' meaning the understanding part of the mind lies nowhere else than in representatives in the next life. Frequently there, in the world of spirits, horses which display great variety are seen, and also people seated on horses. And whenever they are seen the understanding is meant by them. Such representatives are of constant occurrence among spirits. It is because the horse is a representative of the understanding that when horses are mentioned in the Word the spirits and angels present with man know instantaneously that it is the understanding which is being spoken of. It is also why, when spirits from some other planet who have been endowed with intelligence and wisdom are raised up from the world of spirits into heaven, horses shining as though they consisted of fire appear, which I also have seen when those people were carried up.

[2] This experience has made clear to me what is meant by the fiery chariot and the fiery horses which Elisha saw when Elijah went up with the whirlwind into heaven, and what also by Elisha's shout at that time,

My father, my father, the chariot of Israel, and its riders. 2 Kings 2:11-12,

and by the same spoken by Joash king of Israel to Elisha when the latter was dying,

My father, my father, the chariot of Israel, and its riders. 2 Kings 13:14.

In the Lord's Divine mercy it will be shown elsewhere that Elijah and Elisha represented the Lord as to the Word. That is to say, it will there be shown that the doctrine of love and charity drawn from the Word is meant by 'the fiery chariot', and the doctrine of faith deriving from these by 'the fiery horses'. The doctrine of faith is the same as an understanding of the Word as to its inner content, which is the internal sense.

[3] As regards chariots and horses being seen in heaven among spirits and angels, this is evident not only from the fact that they were seen by the prophets, such as by Zechariah (1:8-10; 6:1-7) and by others, but also by Elisha's servant, of whom the following is said in the Book of Kings,

Jehovah opened the eyes of Elisha's servant, and he saw; and behold the mountain was full of horses, and there were fiery chariots surrounding Elisha. 2 Kings 6:17.

Furthermore, where the intelligent and wise dwell in the world of spirits, chariots and horses are constantly making their appearance, the reason being, as has been stated, that chariots and horses represent the things that belong to wisdom and intelligence. People who have been awakened after death and are entering the next life see represented to them a young man seated on a horse, who then dismounts. The meaning of this is that before they can enter heaven they have to be furnished with cognitions of good and truth - see Volume One, in 187, 188. The fact that chariots and horses meant those things was fully known in the Ancient Church, as becomes clear also from the Book of Job, a book of the Ancient Church, where these words occur,

God has made him forget wisdom and given him no share in intelligence. After raising himself on high he laughs at the horse and its rider. Job 39:17-19.

[4] The meaning of 'a horse' as the understanding spread from the Ancient Church to the wise in surrounding regions, and even into Greece. As a consequence of this, when describing the sun, which meant love, 2441, 2495, they placed the god of their wisdom and intelligence there in the sun, and gave him a chariot and four fiery horses. And when they described the god of the sea - the sea meaning knowledge in general, 28, 2120 - they gave horses to him also. And when they described the upsurge of knowledge from the understanding they portrayed it as a flying horse which with its hoof broke open a fountain where the virgins who were the branches of knowledge dwelt. And by the Trojan horse nothing else was meant than a device of their understanding for destroying city walls. Even today, when the understanding is being described, it is quite usual, drawing on the custom received from those people of old, to portray the understanding as a flying horse or Pegasus, and to portray learning as a fountain. Yet scarcely anyone knows that 'a horse' in the mystical sense means the understanding, and 'a fountain' truth, let alone that those images with a spiritual meaning spread to the gentiles from the Ancient Church.
