420. On the earth, nor on the sea, nor on any tree.- That this signifies everywhere in the spiritual world, even to its ultimates, with those in whom there is any perception, is evident from the signification of "the earth," as denoting the whole spiritual world, and therefore, all the angels and spirits there; for earth in its general and most evident meaning, has this signification, because in the spiritual world just as in the natural, there are lands (terroe), mountains, hills, plains, valleys, and also seas; concerning which see above (n. 304:3, 342:3, 413:4), and from the signification of "the sea," as denoting the ultimates of the land (terra) in the spiritual world, because the ultimate boundaries there are seas, concerning which see above (n. 342), and from the signification of a tree, as denoting perception and also knowledge, of which we shall speak presently. Because the earth, the sea, and a tree, signify such things, therefore all three, embraced under one meaning, signify everything in the spiritual world, even to its ultimates, with those in whom there is any perception. A tree signifies in general, perception and cognition, because a garden signifies intelligence, and all intelligence is proportionate to cognitions and the perception of them, and therefore each distinct species of trees signifies something pertaining to knowledge (scientia) and intelligence. Since a tree in general signifies perception and cognition, it therefore also signifies the interiors of man's mind, and also the whole man, for a man's quality is such as the interiors of his mind are, and these are according to his perception from cognitions. That a tree signifies the interiors of man's mind, and also the man himself, may be seen above (n. 109, 110); that a tree signifies perception and cognition, see, Arcana Coelestia 103, 2163, 2682, 2722, 2972, 7692). That the ancients had divine worship in groves under trees, according to their significations (n. 2722, 4552); that this was not allowed to the Jewish nation, and the reasons (n. 2722); that paradises and gardens signify intelligence (n. 100, 108, 3220); also in Heaven and Hell (n. 176), and above (n. 110).

3887. In heaven or the Grand Man there are two kingdoms, one called celestial, the other spiritual. The celestial kingdom consists of angels who are called celestial and are those who have been governed by love to the Lord and so by all wisdom. For they more than all others abide in the Lord and so more than all others experience the state of peace and innocence. To others they look like young children, for the state of peace and innocence gives them this appearance. Everything there is living so to speak in their eyes, for that which comes directly from the Lord is living. Such is the celestial kingdom. The second kingdom is called spiritual. This consists of angels who are called spiritual and are those who have been governed by the good that flows from charity towards the neighbour. The delight of life is considered by them to lie in being able to do good to others without reward. To them being allowed to do good to others is itself a reward. And the more this is their will and desire the greater the intelligence and happiness they experience, for in the next life the Lord confers intelligence and happiness on everyone according to the use which he performs from the affection that belongs to his will. Such is the spiritual kingdom.

[2] Inhabitants of the Lord's celestial kingdom all belong to the province of the heart, and those of His spiritual kingdom all belong to the province of the lungs. The influx from the celestial kingdom into the spiritual kingdom is similar to the influx of the heart into the lungs, and also to the influx of all things belonging to the heart into those belonging to the lungs. For the heart reigns in the whole of the body and in every individual part of it by means of the blood vessels, as do the lungs in every individual part by means of the breathing. Consequently throughout the body there is so to speak an influx of the heart into the lungs, but this is dependent on the forms there and on the states. This is how all sensation arises and also all activity which belongs properly to the body. This point can also be proved from embryos and new-born infants. These cannot have any bodily sensation or any act of individual will until the lungs have been opened for them and an influx consequently takes place of heart into lungs. It is similar in the spiritual world, the difference being that bodily and natural things do not exist in that world but celestial and spiritual, which are the good of love and the good of faith. With them therefore motions of the heart are determined by the states of love, and respiratory motions by the states of faith. The influx of one into the other causes them to have sensations of things in a spiritual manner and to act in a spiritual manner. These ideas are bound to seem paradoxical to man because he has no other idea of the good of love or of the truth of faith than that they are some abstract qualities which have no power to effect anything. In fact the contrary is the case; that is to say, they are the source of all perception and sensation, of all energy and activity, including those in man.
