2. Before treating of the New Jerusalem and its doctrine, something shall be said of the New Heaven and the New Earth. In the small work on The Last Judgment and the Destruction of Babylon it was shown what is meant by the "first heaven and the first earth" which had passed away. After they had passed away, and thus after the Last Judgment had been accomplished, the new heaven was created, that is, formed by the Lord. This heaven was formed of all those who after the Lord's advent even to the present time, had lived a life of faith and charity; since they alone were forms of heaven. For the form of heaven, according to which all consociations and communications are there effected, is the form of Divine Truth from the Divine Good which proceeds from the Lord; and this form a man puts on as to his spirit by a life according to Divine Truth.

That the form of heaven is from this source, may be seen in the work Heaven and Hell 200-212; and that all angels are forms of heaven, in Heaven and Hell 51-58, 73-77. From this it may be known, of whom the new heaven was composed, and hence also what its quality is; namely, that it is altogether of one mind; for he, who lives a life of faith and charity, loves another as himself, and through love conjoins him to himself, and thus reciprocally and mutually, because love in the spiritual world is conjunction. When, therefore, all act alike, then from many, yea, from countless numbers consociated according to the form of heaven, there arises one mind, and there results, as it were, a one; for there is nothing which separates and divides, but everything conjoins and unites.

1413. 'To the land which I will cause you to see' means the spiritual and celestial things that were to be brought to view. This is clear from the meaning of 'a land', 662, 1066, and indeed from the meaning here of 'the land of Canaan' which represents the Lord's kingdom, as becomes clear from many places in the Word. For this reason the land of Canaan is called the Holy Land, and also the heavenly Canaan. And since it represented the Lord's kingdom, it also represented and meant the celestial and spiritual things that belong to the Lord's kingdom, and here those that belong to the Lord Himself.

6032. 'And was seen towards him' means perception. This is clear from the meaning of 'seeing' as understanding and discerning, dealt with in 2150, 3764, 4567, 4723, 5400, and as having faith, 1315, 1807, 3863, 3869, 4403-4421, 5400. As regards the meaning of 'seeing' as understanding and therefore perceiving, and also as having faith, it should be recognized that a person has two components constituting his life - SPIRITUAL LIGHT and SPIRITUAL HEAT. Spiritual light constitutes the life of his understanding, and spiritual heat the life of his will. By virtue of its very own origin spiritual light is Divine Truth flowing from the Lord's Divine Good and is therefore the truth of faith flowing from the good of charity, while spiritual heat by virtue of its very own origin is the Divine Good of the Lord's Divine Love and is therefore the good of celestial love or love to the Lord and the good of spiritual love or love towards the neighbour. As has been stated, these two constitute the entire life in a person.

[2] As regards spiritual light, this is related to a person's understanding in the way that natural light is related to his external sight. That is to say, so that the eye can function, light must exist which enables it to do so. When it exists the eye beholds in that light everything all round outside itself. The same is true of the intellectual power of the mind, which is a person's inner eye. So that this eye can function the light of heaven flowing from the Lord must exist, enabling it to do so. And when this eye functions with the aid of that light it too beholds things all round outside itself. But the objects it sees are spiritual ones - facts and truths. When however it does not have the aid of that light, a person's intellectual power of the mind or inner eye is like his external or physical eye when this is in darkness and cannot see anything. That is, it does not from factual knowledge behold any truth, or from truth behold any good. The light which enables the intellectual power of the mind to function is light indeed, a kind of light which is a thousand times brighter than midday light in the world, as I can testify since I have beheld it. In that light all the angels in heaven see things all round outside themselves, and in that same light they also behold and perceive the truths of faith and the essential nature of them. This now explains why in the spiritual sense 'seeing' means not only the understanding but also any of its activities, such as cogitation, reflection, observation, circumspection, and many others, as well as meaning not only faith but also anything constituting faith, such as truth, teaching drawn from the Word, and the like.

[3] As regards spiritual heat however, this is related to a person's will in the way natural heat is related to his body, in that the one imparts life to the other. But by virtue of its very origin - an origin that can be traced back to the Lord - spiritual heat is nothing other than Divine Love towards the entire human race and the reciprocation of that love by man, to Him and also towards the neighbour. And that heat is heat indeed; it blesses angels' bodies with warmth and at the same time blesses their inmost beings with love. This is the reason why 'heat', 'flame', and 'fire', when used in the genuine sense in the Word, mean things connected with love, such as affections for goodness and truth, and also goodness itself.
