9103. 'And four of the flock for the member of the flock' also means the corresponding punishment carried out in full. This is clear from the meaning of 'four' as joined together, for 'four' is similar in meaning to 'two' because four is the product of two times two (for the meaning of 'two' as joined together, see 5194, 8423, and therefore also 'four', 1686, 8877), from which it follows that those numbers also mean to the complete amount, since what has been joined together is complete; and from the meaning of 'a member of the flock' as interior good, dealt with just above in 9099. The corresponding punishment is meant by 'repaying', at this point 'four of the flock for one member of the flock', 9102. Interior good is what charity in the interior man is called, exterior good being charity in the exterior man. The latter good must receive life from the former, for the good of charity in the interior man is the good of spiritual life, and the good of charity in the exterior man is the good of natural life from the spiritual. This exterior good enters a person's feelings as delight, but not so interior good. Instead this enters his awareness that it ought to be so, and enables his mind to feel contented. In the next life however interior good too enters into a person's feelings.

[2] No one can know the reason why five oxen were to be used in repayment for an ox, and four of the flock for the member of the flock, unless he knows what 'theft' is in the spiritual sense, and also what 'an ox' and 'a member of the flock' are. What these things mean has been explained, namely taking away and alienating exterior and interior good, the taking away being done by evil and the alienation by falsity. Consequently punishment and the restoration of them are meant by 'five' end 'four'; for all numbers in the Word serve to mean spiritual things, see 575, 647, 648, 755, 813, 1963, 1988, 2075, 2252, 3252, 4264, 4495, 4670, 5265, 6175, at this point things having to do with restoration. That is to say, the number 'five' refers to restoration of exterior good to a great degree, and the number 'four' to restoration of interior good in full. The reason why interior good must be restored completely is that this good constitutes a person's spiritual life; and unless his spiritual life is restored completely the exterior good constituting his natural life cannot be restored; for the latter life is restored by means of the former, as may be recognized from a person's regeneration. The external man is regenerated by means of the internal, see 9043, 9046, 9061; but good in the external or natural man cannot be restored completely because the blow it has been struck remains there as a scar that becomes hardened. These are the things implied by those numbers.

[3] Something further must be said briefly about the restoration of the exterior good constituting a person's natural life by means of the interior good constituting his spiritual life. The natural level of a person's mind sees things in the light of the world, the light that is called natural illumination. A person acquires this illumination through objects entering his awareness by means of sight and hearing, that is, by impressions of objects received from the world. Thus the person sees those objects with his mind's eye almost exactly as his physical eye sees them. Initially the objects that he is made aware of through those senses are all a pleasure and delight to him. Later on, when still a young child, he makes distinctions among the objects that are a delight to him, and thereby learns to discriminate, gradually doing so more and more accurately. When the light from heaven flows into these things the person begins to see them spiritually, discriminating initially between the ones that are useful and those that are not useful. As a consequence he starts to see the truth clearly; for that which he sees to be useful he sees to be true, and that which he does not see to be useful he sees to be not true. This ability to see truth increases as the inflowing light from heaven grows brighter, until eventually he discriminates not only between truths, but even between truths within these truths. And this he does ever more clearly, as the communication between the internal man and the external man is improved and opened up; for the light of heaven flows in from the Lord through the internal man into the external. From this the person now has perception; nevertheless this is still not spiritual perception.

[4] Spiritual perception does not grow out of natural truths but out of spiritual truths, spiritual truths being what are called the truths of faith. The reason why spiritual perception grows out of these truths is that the light of heaven is Divine Truth emanating from the Lord. It is the light that shines for the angels' eyes; it also shines in their understanding and imparts intelligence and wisdom to them, in varying amounts, depending on its reception within good. Therefore, if spiritual perception is to grow a person must have cognitions or knowledge of spiritual things in his natural, and such knowledge of spiritual things must come from revelation. When the light of heaven flows into them it flows into what are its own; for as has been stated, that light is Divine Truth emanating from the Lord, see 1053, 1521-1533, 1619-1632, 2776, 3138, 3167, 3195, 3222, 3223, 3341, 3636, 3643, 4180, 4302, 4408, 4415, 4527, 5400, 6032, 6313, 6608. This is how a person acquires intelligence and wisdom in such matters as belong to eternal life; and they increase in the measure that such light - that is, in the measure that the truths of faith - are received within good, the good being charity.

[5] The fact that the natural or external man is regenerated, and also undergoes amendment and is restored by means of the internal, may be recognized from what has now been stated. Things in the external or natural man receive life from the light of heaven; for this light is living, because it emanates from the Lord, who is Life itself. They do not receive their life from natural light, since this light is in itself dead. If therefore things in natural light are to have life there must be an inflow of the living light, coming from the Lord through the internal man. This inflow adjusts itself to cognitions of truth present in the natural that are analogous and correspond, and to other things there that can serve. From this it is evident that a person's external or natural must be regenerated by means of his internal; and the good in the natural that has been taken away or alienated has to be amended and restored by the same means.

3223. There are two forms of light that give light to man, the light of the world and the light of heaven. The light of the world comes from the sun, the light of heaven from the Lord. The light of the world is intended for the natural or external man, and so for things that exist within the natural man. Although these things do not appear to belong to that light, nevertheless they do, for the natural man is not able to grasp anything except by means of such things as occur and are visible in the world of the natural sun, thus unless they are given some visible form by the light and the shade of that world. All concepts of time and concepts of space, which in the natural man play so great a role that without them he is incapable of thought, belong also to the light of the world. The light of heaven however is intended for the spiritual or internal man. Man's interior mind, where his intellectual concepts reside that are called immaterial, belongs in that light. Of this no one is immediately conscious even though he refers to his intellect as sight and attributes light to it. The reason why he is not immediately conscious of it is that as long as he is engrossed in worldly and bodily interests his perception is solely of such things as belong to the light of the world and not of such as belong to the light of heaven. The light of heaven comes from the Lord alone, and the whole of heaven is bathed in that light.

[2] This light - the light of heaven - is immeasurably more perfect than the light of the world. Things which in the light of the world make a single ray make myriads in the light of heaven. The light of heaven holds intelligence and wisdom within it. This is the light which flows into the light of the world which shines in the external or natural man and causes the latter to perceive things with the senses. Unless the light of heaven were flowing in a person would have no discernment at all, for the life present in things which belong to the light of the world is received from that inflowing light. Between these two forms of light - that is, between things that belong to the light of heaven and those that belong to the light of the world - a correspondence exists when the external or natural man makes one with the internal or spiritual man, that is, when the external man is subservient to the internal. In this case things that occur in the light of the world are representative of such as occur in the light of heaven.
