527. "So that the day shone not for a third part of it, and the night likewise." - That these words signify that the spiritual light of truth and the natural light of truth were altogether extinguished, is evident from the signification of day, which denotes spiritual light, and from the signification of night, which denotes natural light. These things are signified, because it was said above, that the third part of the sun, the third part of the moon, and the third part of the stars, were darkened, and by day is meant the light of the sun, and by night, the light of the moon and stars, because the sun gives light during the day, and the moon and the stars give light in the night. Something shall first be said concerning light from the sun, which is called the light of the day, and concerning light from the moon and the stars, which is called the light of the night.

[2] Light from the sun, which is called the light of the day, and also day, means spiritual light, such as the angels enjoy who see the Lord as a sun; and light from the moon and stars, called the light of the night, and also night, means natural light (lux naturalis), such as the angels enjoy who see the Lord as a moon. That the Lord appears to the angels as a sun, and also as a moon, may be seen in the Heaven and Hell 116-125). Those heavens that are in the spiritual affection of truth, that is, who love truth because it is truth, behold the Lord as a sun; and because this is spiritual, therefore the light which is from the Lord as a sun is spiritual. But those heavens that are in the natural affection of truth, that is, who love truth in order to be learned and to instruct others, behold the Lord as a moon, these being in the love of it for the sake of what is useful for themselves, and not for the sake of truth itself, they are therefore in the light which proceeds from the Lord as a moon. This light differs from that which proceeds from the Lord as a sun, as the light of day from the sun differs from the light of the night from the moon and stars in our world. Just as the lights with them differ, so also do the truths, because the Divine Truth proceeding from the Lord is the cause of all light in the heavens; see in the Heaven and Hell 126-140).

[3] Those therefore who are in spiritual light, are in genuine truths, and also when they hear truths, which they did not know before, they at once acknowledge them, and perceive that they are truths. It is different with those who are in natural light; these, when they hear truths, receive them because they are uttered by men of reputation, in whom they repose confidence, although they do not see and perceive [them to be truths]; most of these therefore are in faith from others, but still in a life according to faith. Into these heavens all those come who have lived well, although they have been in falsities of doctrine; nevertheless falsities are there continually purified, until at length they appear as truths. From these considerations the signification of the day shining not for a third part thereof, and the night likewise, is evident. That the third part signifies all, fulness and completeness, may be seen above (n. 506).

[4] The signification of day and night here is similar to that of day and night in the first chapter of Genesis; where it is said:

"God said, Let there be light; and there was light. And God saw the light, that [it was] good; and God divided between the light and the darkness. And God called the light Day, and the darkness he called Night. And there was evening and there was morning the first day" (1:3, 4, 5).

Afterwards it is said:

"And God said, Let there be luminaries in the expanse of the heavens to divide between the day and the night and they shall be for signs, and for seasons, and for days, and years. And God made two great luminaries; the great luminary to rule the day, and the lesser luminary to rule the night; and the stars. And God set them in the expanse of the heavens to give light upon the earth; and to rule over the day and over the night, and to divide between the light and between the darkness. And there was evening and there was morning, the fourth day" (1:14-19).

The light which was made on the first day, signifies Divine light, which in itself and in its essence is Divine Truth, thus spiritual light, which enlightens the understanding. The subject treated of in that chapter, in the internal sense, is the establishment of a church by the Lord amongst the most ancient people. And because the understanding must first be enlightened, for without such enlightenment from the Lord there can be no reformation, consequently no church in man, therefore light is first spoken of, or it is said that there was light [lux] on the first day. The words "God saw the light, that it was good," signify that enlightenment and reception with them was good. But darkness signifies the light [lumen] which is in the natural man, which is also called natural light (lumen naturale); because this light compared with spiritual light (lux spiritualis) is like darkness, it is therefore meant by darkness.

For every man has a lower or exterior mind, and a higher or interior mind; the lower or exterior mind is the natural mind, and is called the natural man, but the higher or interior mind is the spiritual mind, and is called the spiritual man. The reason why the mind is called the man, is, because man is man by virtue of mind. These two minds, the higher and lower, are perfectly distinct. Man by means of the lower mind, is in the natural world, together with men there, but by means of the higher mind he is in the spiritual world with the angels there. These two minds are so distinct, that man while in the world does not know what takes place in his higher mind, and when he becomes a spirit, which is immediately after death, he does not know what takes place in his lower mind. It is therefore said that God divided between the light and between the darkness, and called the light day, and the darkness night. It is consequently evident that day signifies spiritual light (lux spiritualis), and darkness, natural light (lux naturalis). Because all the heavens are so distinct, that those who are in spiritual light may be in light from the Lord as a sun, and those who are in spiritual natural light may be in light from the Lord as a moon, as was said in the article above, it is therefore said, "Let there be two luminaries in the expanse of the heavens to divide between the day and between the night, and to rule in the day and in the night, and to divide between the light and the darkness." From these things, therefore, it is evident that by day is there meant spiritual light, and by night, natural light, which in heaven is called spiritual-natural light.

[5] Similar things are signified by day and night in the following passages.

In David,

Jehovah "who by understanding made the heavens, who spreadeth forth the earth above the waters, who made great luminaries, the sun to rule by day, the moon and stars to rule by night" (Psalm 136:5-9).

So in Jeremiah:

"Jehovah giveth the sun for a light of the day, and the statutes of the moon and of the stars for a light of the night" (31:35).

Again, in David:

"The day is thine, Jehovah, the night also is thine; thou hast prepared the light and the sun" (Psalm 74:16).

And in Jeremiah:

"If ye shall have rendered void my covenant of the day, and my covenant of the night, and that there shall not be day and night in their season; my covenant also may be broken with David my servant, that he shall not have a son to reign upon his throne, and with the Levites the priests, my ministers. If I shall not have fixed my covenant of the day and of the night, and the statutes of the heaven and the earth; then cast I away the seed of Jacob and David" (33:20, 21, 25, 26).

Here by the covenant of the day, and the covenant of the night, are meant all the statutes of the church, prescribed to the children of Israel in the Word, by means of which they had conjunction with heaven, and by means of heaven with the Lord. They are called the covenant of the day and of the night, because they are for heaven and also for the church, the spiritual things which are represented and signified being for heaven, and the natural things which are representative and significative being for the church. Therefore the covenants of the day and of the night are there called the statutes of the heaven and the earth, and the covenant of the night is called the statutes of the moon and stars; to render void, signifies not to keep. That no otherwise would there be conjunction with the Lord by the Divine Truth, nor by the Divine Good, is signified by, "My covenant with David my servant also shall not be broken, that he shall not have a son to reign upon his throne, and with the Levites the priests, my ministers." The covenant with David denotes conjunction with the Lord by means of the Divine Truth, no son upon his throne denotes no reception of the Divine Truth by any one, and the covenant with the Levites the priests, my ministers, denotes conjunction with the Lord by means of the Divine Good.

[6] So again, in David,

"If I say, Surely the darkness shall cover me; even the night shall be light for me. Yea, the darkness shall not make darkness before thee; but the night shall be as bright as the day; as the darkness so the light" (Psalm 139:11, 12).

These words signify that the natural man equally as the spiritual is enlightened by the Lord. Natural light is signified by darkness and night; and spiritual light, by light and day; "the night shall be as bright as the day, and as the darkness so the light" signifies the same as these words in Isaiah:

"The light of the moon shall be as the light of the sun" (30:26).

These things are said in order that it may be known, that by the day which shone not for the third part of it, is signified spiritual light, and by the night which shone not in like manner, is signified natural light, thus that they have the same signification as light from the sun, and light from the moon.

109. To him that overcometh will I give to eat of the tree of life. That this signifies that he who receives in the heart shall be filled with the good of love, and hence with heavenly joy, is evident from the signification of overcoming, as being to receive in the heart, concerning which we shall treat in what follows; and from the signification of eating, as being to appropriate and to be conjoined (concerning which see Arcana Coelestia 2187, 2343, 3168, 3813, 5643); and from the signification of the tree of life, as being the good of love, and thence heavenly joy, concerning which also we shall speak presently. The reason why to overcome denotes to receive in the heart is, that everyone who is about to receive spiritual life will fight against the evils and falsities of his natural life, and when he overcomes them, then goods and truths, which belong to the spiritual life, are received in the heart (to receive in the heart is to receive in the will and love, for the heart in the Word signifies the will and love, as may be seen, Arcana Coelestia 2930, 3313, 7542, 8910, 9050, 9113, 10336); wherefore to receive goods and truths in the heart, is to do them from the will or love; this is what is meant by overcoming.

[2] The reason why the tree of life signifies the good of love, and thence heavenly joy is, that trees signify those things that are internally in man, which pertain to his interior mind (mens), or his external mind (animus), the boughs and leaves those things which pertain to the knowledges (cognitiones) of truth and good, and the fruits the goods of life themselves. This signification of trees originates in the spiritual world; for in that world trees of all kinds are seen; and these trees correspond to the interiors of the minds of angels and spirits; beautiful and fruitful trees to the interiors of those who are in the good of love, and thence in wisdom; trees less beautiful and fruitful to those who are in the good of faith; but trees bearing leaves only, and without fruit, to those who are only in the knowledges (cognitiones) of truth; and trees of a dismal hue, with malignant fruits, to those who are in knowledges (cognitiones) and in evil of life; but by those who are not in knowledges, and are in evil of life, trees are not seen, but instead stones and sand.

These appearances in the spiritual world, actually flow from correspondence; for the interiors of the mind of the inhabitants of that world are by such forms actually presented before their eyes. (These things may be seen better from two articles in the work, Heaven and Hell; in the first, where the correspondence of heaven with all things of the earth is treated of, n. 103-115; and in the other, where representatives and appearances in heaven are treated of, n. 170-176, and n. 177-190.)

[3] This then is why trees are so often mentioned in the Word, by which are signified those things which pertain to a man's mind; and why it is, that in the first chapters of Genesis, two trees are said to have been placed in the garden of Eden, one of which was called the tree of life, and the other the tree of knowledge (scientia). By the tree of life mentioned there is signified the good of love to the Lord, and thence heavenly joy, which those possessed who at that time formed the church, and who are meant by the man and his wife; and by the tree of knowledge is signified the delight of knowledges (cognitiones) without any other use than to be accounted learned, and to acquire renown for erudition, solely for the sake of honour or gain. The reason why the tree of life also signifies heavenly joy is, because the good of love to the Lord, which is specifically signified by that tree, has heavenly joy in it. (See the work, Heaven and Hell 395-414, and The Doctrine of the New Jerusalem 230-239.)

[4] That trees, so often mentioned in the Word, signify the interiors of man's internal and external minds, and the things produced by the trees, as the leaves and fruit, such things as are derived from them, is evident from the following passages:

"I will give in the desert the cedar, the schittah tree, and the myrtle, and the oil tree; I will set in the wilderness the fir tree, the pine and the box" (Isaiah 41:19).

The establishment of the church is there treated of;

"The glory of Lebanon shall come unto thee, the fir tree, the pine tree, and the box together, to beautify the place of my sanctuary" (Isaiah 60:13).

"Let all the trees of the field know that I, Jehovah, humble the lofty tree, and exalt the humble tree, cause the green tree to become dry, and make the dry tree to bud" (Ezekiel 17:24).

"Behold, I will kindle a fire in thee, and it shall consume every green tree in thee, and every dry tree" (Ezekiel 20:47).

"The vine is dried up, and the fig tree languisheth; the pomegranate tree, the palm tree also, and the apple tree, all the trees of the field are withered, because joy is withered away from the sons of men" (Joel 1:12).

"When the angel sounded, there followed hail and fire which fell upon the earth; and the third part of the trees was burnt up" (Apoc. 8:7)

Nebuchadnezzar saw in a dream "a tree in the midst of the earth, and the height thereof was great, the leaf thereof fair, and the flower thereof much, and in it was food for all" (Dan. 4:10-12).

Because trees in general signify such things as pertain to man, and constitute the interiors of his mind, and thus the spiritual things pertaining to the church, and both the latter and the former are various, therefore so many species of trees are mentioned, and every species signifies something different. (What the various species signify is shown in Arcana Coelestia, as what is signified by the oil tree, n. 9277, 10261 what by the cedar, n. 9472, 9486, 9528, 9715, 10178 what by the vine, n. 1069, 5113, 6375, 6378, 9277; what by the fig, n. 217, 4231, 5113, and so forth.)

[5] Moreover, the things which are upon trees, as leaves and fruits, signify those things that pertain to man; leaves signify the truths pertaining to him, and fruits the goods, as in the following passages:

"He shall be as a tree planted by the waters, and that spreadeth out her roots by the river; her leaf shall be green; neither shall it cease from yielding fruit" (Jeremiah 17:8).

By the river which went out from the house of God "upon the bank thereof, on this side and on that side, ascendeth the tree of food, whose leaf falleth not off, nor is its fruit consumed; it springeth again in its months, because its waters issue out of the sanctuary, whence its fruit is for food, and its leaf for medicine" (Ezekiel 47:12).

"In the midst of the street of it, and of the river (going out from the throne of God and the Lamb), on this side and on that side, was there the tree of life bearing twelve fruits, and yielding her fruit every month, and the leaves of the tree are for the healing of the nations" (Apoc. 22:1, 2).

"Blessed is the man whose delight is in the law; he shall be like a tree planted by the rivers of water, that bringeth forth his fruit in his season, his leaf also shall not wither" (Psalms 1:1-3).

"Be not afraid, for the tree shall bear her fruit, the fig tree and the vine shall yield their strength" (Joel 2:22).

"The trees of Jehovah are full of sap, the cedars of Lebanon which he hath planted" (Psalms 104:16).

"Praise Jehovah, ye fruitful trees, and all cedars" (Psalms 148:9).

[6] Because fruits signified the goods of life with man, therefore in the Israelitish church, which was a representative church, it was commanded that the fruit of trees, like the men themselves, should be circumcised, concerning which it is thus written: The fruit of a tree serving for food shall be uncircumcised in the land of Canaan;

"three years shall it be uncircumcised unto you; and in the fourth year all the fruit thereof shall be holy, the praises of Jehovah. And in the fifth year shall ye eat of the fruit thereof" (Leviticus 19:23, 24, 25).

Because the fruit of the tree signified goods of life, therefore also it was commanded, that

in the feast of tabernacles they should take the fruit of the tree of honour, and the boughs, and should rejoice before Jehovah, and thus they should keep the feast (Leviticus 23:40, 41);

for by tabernacles were signified the goods of celestial love, and thence holy worship (see Arcana Coelestia 414, 1102, 2145, 2152, 3312, 4391, 10545); and by the feast of tabernacles was signified the implantation of that good of love (n. 9296). Because fruit signified the goods of love, which are the goods of life, therefore it was among the blessings that the tree of the field should yield its fruit; and among the curses that it should not yield its fruit (Leviticus 26:4, 20). And therefore also they were forbidden, when any city was besieged, to lay the axe to any tree of good fruit (Deuteronomy 20:19, 20).

From these considerations it is now evident that by fruits are signified the goods of love, or, what is the same, goods of life, which are also called works, as also what is meant in these passages in the Evangelists:

"The axe lies at the root of the trees; every tree which bringeth not forth good fruit shall be hewn down and cast into the fire" (Matthew 3:10; 7:16-21).

“Either make the tree good and the fruit good, or else make the tree corrupt and the fruit corrupt; for the tree is known by its fruit" (Matthew 12:33; Luke 6:43, 44).

"Every branch in me that beareth not fruit shall be taken away: but every branch that beareth fruit shall be purged, that it may bring forth more fruit" (John 15:2-8).

"A certain man had a fig-tree planted in his vineyard: he came seeking fruit thereon, and found none. Then saith he unto the vinedresser, Behold, these three years I come seeking fruit on the fig-tree, and find none: cut it down; why cumbereth it the ground?" (Luke 13:6-9).

"Jesus saw a fig-tree in the way; he came to it, and found nothing thereon but leaves only; he said, Let no fruit grow on thee for ever. And immediately the fig tree withered away" (Matthew 21:19; Mark 11:13, 14, 20).

By the fig-tree is signified the natural man and his interiors, and by the fruit his goods (see Arcana Coelestia 217, 4231, 5113); but leaves signify knowledges (cognitiones), (n. 885). Hence it is clear what is signified by the fig-tree withering away, because the Lord found on it leaves only, and no fruit. All these passages are quoted in order that it may be known that by the tree of life in the midst of the paradise of God, is signified the good of love proceeding from the Lord, and heavenly joy therefrom.
