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.

9905. 'And you shall put into the breastplate of judgement the Urim and Thummim' means the radiance of Divine Truth from the Lord in last and lowest things. This is clear from the meaning of 'the breastplate of judgement' as Divine Truth shining forth from the Lord's Divine Good, dealt with in 9857; and from the meaning of 'the Urim and Thummim' as the light and radiance from there. The reason why light and radiance are meant by 'the Urim and Thummim' is that through the stones in the breastplate varying radiations of the light of heaven were emitted, these being determined by the answers given through them. This also explains why they assumed different colours. For the Divine Truth emanating from the Lord's Divine Good manifests itself to the angels as light; it is the source of all the light of heaven. The colours from it, which are modifications of that light among the angels, are variations of intelligence and wisdom among them; for all wisdom and intelligence is a product of that Divine Truth or light. From this it may be recognized that radiations of that light in various colours are the medium through which Divine Truths coming as answers present themselves in the heavens. A similar function was served by the Urim and Thummim when God was asked something. But it should be remembered that whenever a radiance was seen in them the answer was declared at the same time by an audible voice. This declaration was made through angels, to whom what they declared had been revealed by the Lord through such a radiance; for as has been stated, this is how Divine Truths coming as answers present themselves in heaven.

[2] The light of heaven is Divine Truth emanating from the Lord's Divine Good, see 1053, 1521-1533, 1619-1632, 2776, 3094, 3138, 3167, 3190, 3195, 3222, 3223, 3337, 3339, 3341, 3636, 3643, 3862, 3993, 4060, 4180, 4302, 4408, 4414, 4415, 4419, 4527, 4598, 5400, 6032, 6313, 6315, 6608, 6907, 7174, 8644, 8707, 8861, 9399, 9407, 9570, 9571 (end).

Colours appear in heaven, being modifications of that light among the angels, and so variations of intelligence and wisdom among them, 3993, 4530, 4677, 4742, 4922, 9466, 9467, 9865.

[3] The meaning of the words 'Urim' and 'Thummim' also goes to show that all this is so; for 'Urim' means a shining fire, and 'Thummim' the radiance from it. A shining fire is the Divine Truth emanating from the Divine Good of the Lord's Divine Love, and the radiance is that Truth on last and lowest levels, thus in effects. It should be recognized however that 'Thummim' in the Hebrew language means wholeness; it is in the angelic language that it means radiance. The expression 'in the angelic language' is used because when angels talk to one another they are thinking of the very essence of some matter as perceived deep within themselves, thus they speak in terms of its essential nature. What they express flows from those insights into appropriate sounds audible to the angels alone. The appropriate sound for the radiance of Divine Truth is Thummim. This then is the source of the term. Angels have a similar understanding of the word thum, meaning that which is whole or wholeness, whenever someone reads it in the Hebrew language. This explains why in the internal sense of the Word 'that which is whole' is used to mean Divine Truth on the level of effects, which is a life led in keeping with Divine commandments, as is made clear in a large number of places in the Word, such as Joshua 24:14; Judges 9:16, 19; Psalms 25:21; 37:37; 84:11; 101:2; 119:1.

[4] This also explains why the Urim and Thummim are called the judgement of the children of Israel, as well as the breastplate of judgement, and also the judgement of the Urim; for 'judgement' means Divine Truth in doctrine and life, see above in 9857. From all this it may now become clear that by means of the Urim and Thummim, that is, by means of the radiance produced by the light of heaven, the breastplate revealed Divine Truths in the natural sphere, thus on last and lowest levels. A like radiance also presents itself in the minds of those who are guided by truths springing from good. This radiance declares to them, so to speak provides the answers, when with heartfelt desire they seek to know what is true and love it as that which is good. That this kind of radiance is the means by which Divine Truth from heaven is revealed in the natural man of those who are enlightened by the Word is something which the world has no idea of, because the world does not know of any light from heaven that shines in the human understanding. But I have been allowed to realize and actually see that all this is so.

[5] In addition it should be recognized that this radiance appears on last and lowest levels because all forms of light from the Divine reach right down to the furthest ends; and since they reach down that far they also shine in them and from them. This now explains why the breastplate was placed over the ephod and above the girdle of it; for the ephod represented Divine Truth on last and lowest levels, 9824, while its girdle represented a common bond that existed to hold all things in connection, 9828, 9837. This is why verse 28 of the present chapter says, And they shall tie the breastplate from its rings to the rings of the ephod, so that it is above the girdle of the ephod and the breastplate will not come away from upon the ephod. The reason why the names of the sons of Israel were in addition engraved [on the stones] was that the twelve tribes also represented all aspects of Divine Good and Truth in the heavens, consequently heaven and all the communities there, though that representation varied according to the order in which they are mentioned in the Word, see 3858, 3862, 3926, 3939, 4060, 4603, 6335, 6337, 6397, 6640, 7836, 7891, 7973, 7996, 7997.
