268. Verse 3. And He that sat was in aspect like to a jasper stone and a sardius, signifies the Lord's appearance in respect to Divine truth pellucid by virtue of the Divine good of the Divine love. This is evident from the signification of "One sitting upon the throne," as being the Lord in respect to the Last Judgment (of which just above, n. 267; and from the signification of "in aspect like," as being appearance; from the signification of "jasper stone," as being the spiritual love of truth (of which in what follows); and from the signification of a "sardius stone" as being the celestial love of good; thus "a jasper stone and a sardius," which the Lord appeared like, signify Divine truth pellucid, by virtue of the Divine good of the Divine love.

[2] That a "jasper" signifies the Divine love of truth, or Divine truth proceeding, is evident from passages in the Word where it is mentioned, as Exodus 28:20; and Ezekiel 18:13; also in Revelation:

The light [luminare] of the holy Jerusalem was like unto a stone most precious, as it were a jasper stone, shining like crystal (Revelation 21:11);

"the light of the holy Jerusalem" signifies the Divine truth of the church shining, "the light" truth itself shining, and "Jerusalem" the church in respect to doctrine; this is likened to "a jasper stone," because "jasper" has a like signification.

Again:

The building of the wall [of the holy Jerusalem] was of jasper, and the city was pure gold, like unto pure glass (Revelation 21:18).

The "wall" of the holy Jerusalem is said to be "of jasper," because "wall" signifies Divine truth guarding; and because of this signification of "wall," the first stone of its foundation is said to be jasper (verse 19), "foundation" signifying the truth upon which the church is founded.

[3] The "sardius" is mentioned because that stone signifies good, here Divine good, because the Lord is described. This is the stone that is called "pyropus" [firestone], and since it shines as by fire, both names signify the translucency of truth from good. (That all precious stones signify the truths from good of heaven and of the church, see Arcana Coelestia 114, 9863, 9865, 9868, 9873; for this reason twelve precious stones were set in the breastplate of Aaron, which is called the Urim and Thummim, and by them responses were given, and this by their shining forth, and at the same time by a perception as to the thing interrogated or by a living voice, n. 9905)

9570. 'And let it cause its lamps to go up' means the light of the spiritual heaven. This is clear from the meaning of 'causing the lamps to go up' as kindling a light in them so that they may give light; and since 'the lampstand' represented the spiritual heaven, 9548, 'causing the lamps to go up' means the light of the spiritual heaven. The light of the spiritual heaven is Divine Truth emanating from the Lord, and the faith, intelligent understanding of truth, and wise discernment of good that spring from it, see the places referred to in 9548. What the light of the spiritual heaven is like must be stated briefly. In the Lord's celestial kingdom, which is the inmost or third heaven, there is light which is vastly superior to the light that exists in the Lord's spiritual kingdom, which is the middle or second heaven. The light of the celestial kingdom or inmost heaven does not have the appearance of light but of flame. The reason for this is that in that heaven the good of love reigns, and the good of love manifests itself visually in heaven as flame, whereas in the Lord's spiritual kingdom, which is the middle or second heaven, there is light which, though vastly superior to the light of the world, nevertheless has the appearance of brilliant light. And the reason why is that in this heaven the truth of faith springing from the good of love reigns, and the truth of faith springing from that good manifests itself visually in heaven as brilliant light. This also explains why 'light' in the Word means truth that springs from good, and in the highest sense Divine Truth emanating from the Lord's Divine Good. From all this it may now become clear what should be understood by the light of the spiritual heaven, and what by the flame of the lamp from which that light shines.
