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.

1616. That 'Abram moved his tent, and came and dwelt in the oak groves of Mamre which are in Hebron' means that the Lord arrived at a perception more interior still is clear from the meaning of 'moving one's tent', that is, moving it and pitching it once again, as the process of being joined together; for 'a tent' is the holiness of worship, as shown already in 414, 1452, by which the external man is joined to the internal. It is also clear from the meaning of 'an oak-grove' as perception, dealt with already in 1442, 1443, where the phrase that occurred was 'the oak-grove of Moreh', meaning a first perception, whereas here the plural 'the oak-groves of Mamre' is used, which means a fuller, that is, more interior perception. This perception is called 'the oak-groves of Mamre which are in Hebron'. Mamre is also mentioned elsewhere in the Word, as in Genesis 14:13; 18:1; 23:17-19; 35:27; and Hebron too, in Genesis 35:27; 37:14; Joshua 10:36, 39; 14:13-15; 15:13, 54; 20:7; 21:11, 13; Judges 1:10, 20; and elsewhere. But what Mamre and Hebron mean where they are so mentioned will in the Lord's Divine mercy be seen when these other parts of the Word are explained.

[2] The implications of 'the oak-groves of Mamre which are in Hebron' meaning perception more interior still are as follows: To the extent that those things belonging to the external man are joined to celestial things belonging to the internal man perception grows and becomes more interior. Conjunction with celestial things confers perception, for within the celestial things that belong to love to Jehovah dwells the life itself of the internal man, or what amounts to the same, within celestial things which belong to love, that is, within celestial love, Jehovah is present. This presence is not perceived in the external man however until the conjunction has taken place. All perception is the result of conjunction.

[3] From the internal sense here it is clear what the situation was in the Lord's case: His External Man, or Human Essence, was joined step by step to the Divine Essence as cognitions multiplied and became fruitful. No one can ever, insofar as he is human, be joined to Jehovah, or the Lord, except by means of cognitions, for it is by means of cognitions that a person is made human. This applied to the Lord too since He was born as any other is born, and received instruction as any other does. Yet in the cognitions He had as receptacles celestial things were being instilled continually, with the result that His cognitions were constantly being made into the recipient vessels of celestial things; and these vessels also were themselves made celestial.

[4] Constantly the Lord advanced in this manner towards the celestial things of infancy, for, as stated already, the celestial things which belong to love are being instilled in a person from earliest infancy to childhood and on into adolescence as well. Since he is a human being, at that time and later on he is endowed with knowledge and cognitions. If a person is such that he can be regenerated, that knowledge and those cognitions are filled with celestial things that belong to love and charity, and are accordingly implanted within the celestial things he was endowed with from infancy through to childhood and adolescence, and in this way his external man is joined to his internal. First of all they are implanted in the celestial things he was endowed with in adolescence, then in those he was endowed with in childhood, and finally in those he was endowed with in infancy. At that point he is 'the little child' regarding whom the Lord said 'of such is the kingdom of God'. This implanting is done by the Lord alone, and therefore nothing celestial with man either does or can exist with man that does not come from, and belong to, the Lord.

[5] The Lord however from His own power joined His External Man to His Internal Man and filled His cognitions with celestial things, and He implanted them in celestial things, doing so according to Divine Order. First of all He implanted them in the celestial things of childhood, then in the celestial things of the age of childhood and back to infancy, and finally in the celestial things of His infancy. In this way He at the same time became as regards the Human Essence Innocence itself and Love itself, from which derive all innocence and all love in heaven and on earth. Such Innocence is true Infancy because it is simultaneously Wisdom. But the innocence of infancy is of no use at all unless by means of cognitions it becomes the innocence of wisdom, and this is why little children in the next life are endowed with cognitions. As the Lord implanted cognitions in celestial things, so He had perception, for, as stated, all perception is the result of conjunction. He had His first perception when He implanted the facts acquired in childhood, a perception meant by 'the oak-grove of Moreh'; and He had His second, which is the subject here, and which is more interior, when He implanted cognitions, a perception meant by 'the oak-groves of Mamre which are in Hebron'.
