167. And all [the churches] shall know that I am he who searcheth the reins and hearts. That this signifies the acknowledgment, on the part of all those who belong to the church, that the Lord alone knows and explores the exteriors and interiors and the things pertaining to faith and love is evident from the signification of searching, when said of the Lord, as being that He alone knows and explores; and from the signification of the reins, as being the truths of faith, and their purification from falsities, concerning which we shall speak in what follows; and from the signification of hearts, as being the goods of love. The reason why the heart signifies the good of love is, that there are two things that reign in man, from which all the life of his body is derived - the heart and the lungs. And because all things in a man's body correspond to all the things in his mind, and there are also two things that reign there, the will and the understanding, therefore these two kingdoms of the mind correspond to the two kingdoms of the body - the will to the heart and its pulse, and the understanding to the lungs and their respiration; without this correspondence the body could not live, nor even a particle of it. Because the heart corresponds to the will, it also corresponds to the good of love; and as the lungs correspond to the understanding, they also correspond to the truths of faith. It is from this correspondence that the heart signifies love, and the soul (anima) signifies faith; hence the expression "from the heart and soul" is so often used in the Word, by which is meant from the love and faith. (This correspondence is much treated of in Arcana Coelestia, where the following particulars may be seen more fully explained, namely, that the heart in the Word signifies love, and because it signifies love, that it also signifies the will, n. 2930, 3313, 7542, 8910, 9050, 9113, 10336. That the heart corresponds to the things that pertain to man's love, and the lungs to the things that pertain to his faith, n. 3883-3896. That in heaven there is a pulse like that of the heart, and a respiration like that of the lungs, n. 3884, 3885, 3887. That the pulse of the heart there is according to the state of love, and the respiration of the lungs according to the state of faith, n. 3886-3889; that the influx of the heart into the lungs is circumstanced like the influx of good into truth, or of the will into the understanding and of love into faith, and that the communications and conjunctions are similar, n. 3884, 3887-3889, 9300, 9495. Concerning the influx of heaven into the heart and into the lungs, from experience, n. 3884. That from this correspondence in the Word, when it is said from the heart and from the soul, it signifies from the love and faith, n. 2930, 9050; that the conjunction of man's spirit with his body is by means of the respiration of the lungs and of the pulse of the heart, and that therefore when these cease, man's body dies, but his spirit lives, see the work, Heaven and Hell; and that when the pulse of the heart ceases, the spirit is separated, because the heart corresponds to love which is the vital heat, n.447, in that work. Many other things concerning that correspondence may be seen there, n. 95.) That the kidneys signify the truths of faith and the purification of them from falsities, is because the purification of the blood is performed in the kidneys; and by blood in the Word is signified truth, as may be seen, Arcana Coelestia. n. 4735, 9127. The same also is signified by the organ which purifies: also all purification from falsities is effected by means of truths.

It is therefore evident that by Jehovah, or the Lord, in the Word, searching the heart and reins is signified that He explores the goods of love and the truths of faith, and separates them from evils and falsities.

[2] This is signified by reins in the following places: in Jeremiah,

"Jehovah Zebaoth, judge of justice, proving the reins and the heart" (11:20).

Again:

"Thou hast planted them, yea, they have taken root: they grow, yea, they bring forth fruit; thou art near in their mouth and far from their reins. Jehovah, thou shalt see me, and shalt prove my heart" (12:2, 3).

By being near in the mouth, and far from the reins is meant truth only in the memory, and thence in some of his thoughts when a man speaks, but not in the will and thence in act. Truth in the will and thence in act is that which separates and dissipates falsities; truth in the will and thence in act is to will and do what a man knows and thinks to be truth; this truth is what is specifically meant by reins.

[3] Again in the same prophet:

"I Jehovah search the heart, and prove the reins, even to give every one according to his ways, and according to the fruit of his works" (17:10).

To search the heart is to purify good by separating evil from it; to prove the reins, is to purify truth by separating falsity from it. It is therefore said, "To give every man according to his ways, and according to the fruit of his works"; ways denote the truths of faith, and the fruit of works denotes the goods of love. (That ways denote truths of faith, may be seen above, n. 97, and that the fruit of works denotes the goods of love, n. 98, 109, 116.)

[4] In the same:

"Jehovah Zebaoth, proving the just, seeing the reins and the heart" (20:12).

And in David:

"Establish the just for thou who triest the hearts and reins art a just God" (Psalms 7:9).

The just denote those who love to do what is good and true, whose truths and goods are purified by the Lord, which is signified by His seeing and trying the reins and the hearts.

In the same:

"Prove me, O Jehovah, and try me, explore my reins and my heart" (Psalms 26:2).

Because truths are separated from falsities and goods from evils by temptations, it is therefore said, try me. In the same:

"For my heart was embittered and I am pricked in my reins. But I am foolish, and I do not know" (Psalms 73:21, 22).

The infestation of good by evil and of truth by falsity, is described by these words.

In the same:

"Behold, thou desirest truth in the reins, and in the hidden part thou makest wisdom known to me" (Psalms 51:6).

Here reins are expressed by another word in the original tongue, which involves the separation both of falsities from truths and of evils from goods. It is therefore evident that the reins signify purification and separation.

[5] In the same:

"I will bless Jehovah, who hath given me counsel; nightly, also, do my reins chastise me" (Psalms 16:7).

Nights signify the state of man when falsities rise up; the combat in such cases of truths with them is signified by "my reins chastise me." In the same:

"Even the darkness doth not make darkness before thee, but the night is light as the day; as the darkness so is the light; for thou possessest my reins, my bone was not hid from thee when I was made in secret" (Psalms 139:12, 13, 15).

Falsities are signified by darkness and truths by light; to possess the reins, is to know the falsities and truths pertaining to man; hence it is said, "my bone was not hid from thee when I was made in secret," which signifies that no falsity that was made could be bid. (That darkness denotes falsities and light truths may be seen in the work, Heaven and Hell 126-140 and that bone signifies truth in the ultimate of order, and, in the opposite sense, falsity, in Arcana Coelestia 3812, 5560, 5565, 6592, 8005.)

[6] Because the reins signified truths purified from falsities, therefore in the sacrifices the fats and reins were alone offered up, as may be seen in Exodus 29:13; Leviticus 3:4, 10, 15; 4:9; and other places.

The reason why the fats and reins alone were offered upon the altar was, because the fats signified the goods of love, and the reins the truths of faith. (That fats or fatnesses signify the goods of love, may be seen, Arcana Coelestia 353, 5943, 6409, 10033. That the reins signify the truths of faith examining, purifying, and rejecting from themselves falsities is from correspondence; for all parts of the body, even the most minute, have a correspondence, as may be seen in the work, Heaven and Hell, where it is shown, under its proper article, that "there is a correspondence of all things of heaven with all things of man," n. 87-102; and concerning the kidneys, n.96, 97.) Unless it be known that there is such a correspondence, who could know why it is so often stated of Jehovah, or the Lord, in the Word, that He searches and tries the reins and the heart? (Concerning the correspondence of the kidneys, the ureters, and vesicles, see Arcana Coelestia 5380-5386.) The reason why to search the reins and the heart also signifies to explore the exteriors and interiors of man is, that truth is without, and good is within; and spiritual good, which in its essence is truth, and which is specifically signified by the reins, is exterior good: but celestial good, which is specifically signified by the heart, is interior good. (This is more evident from what is said and shown concerning, the spiritual kingdom and the celestial kingdom in the work, Heaven and Hell 20-26.)

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.
