4676. 'For he was the son of his old age' means its own life within it. This is clear from the meaning of 'old age' as the casting aside of the previous state and the assumption of the new one, and also as newness of life, dealt with in 3492, 4620. For in the internal sense 'old age' does not mean old age, for the reason that the internal man, or man's spirit, does not know what old age is; but as the body or the external man grows old, so he passes into newness of life. As he ages man's spirit is made more perfect, at the same time as his physical powers diminish. This is truer still in the next life, for those in heaven are constantly being led by the Lord into a more perfect life, and at length into the bloom of youth, including those people who have died at a ripe old age. From these considerations it may be seen that in the internal sense 'old age' means life. What is meant by the expression 'its own life within it' has been explained above in 4667.

[2] Just above it was said that man's spirit or the internal man does not know what old age is, and yet before that it was said that it is in this spirit within the body where thinking takes place, and also that life flows from the spirit to the body. The reason why that thought belonging to the spirit cannot be communicated to the body, enabling the person to know that he lives after death is that as long as his spirit remains within the body he cannot do other than think from the assumptions which his natural man has been adopting. And if he has made the assumption and is convinced that only the body is living and that when this dies the whole human being does so, the influx of that spiritual reality is not received. Evidence of the existence of that influx may nevertheless be seen in the fact that most people are concerned about their own burial and the tributes paid to them after death, some about their reputation then, on account of which they also erect splendid monuments to themselves so that the memory of them may not be lost. These are the kinds of things into which the influx from heaven regarding the continuance of life is channeled by those who otherwise have no belief in that life. Without that influx they would treat with utter disdain all remembrance of themselves after they have died.

1053. That 'and the bow will be in the cloud' means the state of that man is clear from what has been stated and shown already about the bow in the cloud, that is to say, in the next life a person or soul is known among angels from his sphere; and as often as it pleases the Lord that sphere is represented by means of colours like those of the rainbow, variously according to each person's state as to faith in the Lord and thus respectively as to goods and truths of faith. In the next life colours present themselves to view, which on account of their brilliance and splendour are immensely superior in beauty to colours seen with the eyes on earth. Each colour represents something celestial or spiritual.

[2] Those colours derive from the light in heaven, and from the variegation of spiritual light, as stated above. Indeed angels live in light so bright that the light of the world is in comparison no light at all. The light of heaven in which angels live, compared with the light of the world, is as the light of the sun at midday to the light of a candle that is put out and ceases to give any light at all when the sun rises. In heaven there is celestial light and there is spiritual light. Let me compare the two by saying that celestial light is as the light of the sun, while spiritual light is as the light of the moon. But all manner of variation exists depending on the state of the angel receiving the light. The same applies to colours since they are a product of the light. In the heaven of celestial angels the Lord Himself is the Sun, and in the heaven of spiritual angels the Moon. To people who have no conception of the life which souls lead after death these matters are unbelievable. They are nevertheless completely true.
