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.

4408. The existence of a correspondence between the sight of the eye and that of the understanding is perfectly plain to those who stop to reflect, since the objects that make up the world, each of which derives something from the light of the sun, come in through the eye and store themselves in the memory. They deposit themselves there as visual impressions of those objects, for the things which a person recalls from the memory are seen inwardly by him. They are the source of man's formation of mental images, whose constituent ideas philosophers term material ideas. And when a person sees these objects even more inwardly within himself they present themselves as thought, doing so again as something like visual impressions, though purer ones, whose constituent ideas are called immaterial, and also intellectual. The existence of an interior light holding life, and therefore intelligence and wisdom, within it, which provides the light for the interior sight and meets those impressions which have come in through the external sight, is plainly evident, as also is the fact that the action of the interior light is dependent on the way in which things that are present there from the light of the world are deployed. The things which come in through hearing are also converted inwardly into impressions similar to the visual ones which are formed from the light of the world.
