312. So I looked, and behold, a black horse. This symbolizes an understanding of the Word among them extinguished as to truth, thus extinguished as regards their doctrine.

We showed above that a horse symbolizes an understanding of the Word. Blackness symbolizes a lack of truth, thus falsity, because blackness is the opposite of whiteness, and whiteness is predicated of truth (nos. 167, 231, 232). Whiteness is also the result of light, while blackness results from darkness, thus from the absence of light, and light means truth.

In the spiritual world, however, blackness has a double origin, one resulting from the absence of a flaming light, the light possessed by inhabitants of the Lord's celestial kingdom, and the other resulting from the absence of a bright white light, the light possessed by inhabitants of the Lord's spiritual kingdom. The first kind of blackness has the same symbolism as a thick darkness, the second the same as a gloomy darkness. The two kinds differ from each other. One is dreadful, the other not so dreadful. It is the same with the falsities that they symbolize. The spirits who appear in a terrible darkness are called devils. They also abhor truth as owls do the light of the sun. In contrast, the spirits who appear in a darkness that is not so dreadful are called satanic spirits. They do not abhor truth, though they are still averse to it, and therefore they may be likened to barn owls, but the first to eagle owls.

The fact that blackness in the Word is predicated of falsity can be seen from the following passages:

Her Nazirites were brighter than snow... Darkened more than blackness is their form. (Lamentations 4:7-8)

...on the prophets... the day shall grow black. (Micah 3:6)

On the day that you go down to hell..., I will make Lebanon dark over you... (Ezekiel 31:15)

...the sun became as black as sackcloth of goat's hair... (Revelation 6:12)

The sun, moon and stars are darkened in Jeremiah 4:27-28, Ezekiel 32:7, Joel 2:10; 3:15, and elsewhere.

It was the third living creature that displayed the black horse because it had a face like a human being, which symbolized the Divine truth of the Word in respect to its wisdom (no. 243). Consequently it was this living creature that displayed the fact that there was no longer any truth of wisdom in the people who were third in order.

231. And He who sat there was like a jasper and a sardius stone in appearance. (4:3) This symbolizes an appearance of the Lord's Divine wisdom and love in outmost expressions.

In the Word a stone symbolizes truth in outmost expressions, and a precious stone symbolizes truth made translucent by the presence of good (no. 915).

Two colors are fundamental to all the rest in the spiritual world: the color white and the color red. The color white takes its origin from the light of the sun in heaven, thus from spiritual light, which is bright white; and the color red takes its origin from the fire of the sun there, thus from celestial light, which is flaming.

Because spiritual angels are governed by truths of wisdom from the Lord, they live in that bright white light, and are therefore attired in white; and because celestial angels are governed by goods of love from the Lord, they live in that flaming light, and are therefore attired in red. These two colors are consequently found in precious stones in heaven, where they exist in great abundance.

It is owing to this that in the Word precious stones symbolize qualities connected with either the truth of wisdom or the goodness of love; and because jasper is bright white, it symbolizes qualities connected with the truth of wisdom, while because sardius is red, it symbolizes qualities connected with the goodness of love.

These stones symbolize an appearance of Divine wisdom and Divine love in outmost expressions because all precious stones in heaven draw their origin from the outmost constituents of the Word, and they owe their translucence to the spiritual meaning of the outmost expressions in it. The reality of this may be seen in The Doctrine of the New Jerusalem Regarding the Sacred Scripture, nos. 44, 45. The outmost expressions of the Word are the truths and goods in its literal sense.

Someone in our world can hardly believe that this is the origin of precious stones in heaven, because he does not know that everything found in the spiritual world is a correspondent form, and that everything found in the natural world takes its spiritual origin from those forms. From conversation with angels I have been given to know that this is the origin of precious stones in heaven, and also to see that it is the origin with my own eyes. It is the Lord alone, however, who causes their formation.

In contrast, dark colors take their origin from hell, of which there are also two. One is the opposite of white, the kind of darkness that exists with people who have falsified the truths of the Word. The other is the opposite of red, the kind of darkness that exists with those who have adulterated the goods of the Word. The first kind of darkness is satanic, the latter diabolical.

Regarding what jasper and sardius symbolize, more may be seen in the exposition of chapter 21, verses 11, 18-20.
