Apocalypse Revealed #423
423. And the sun and the air were darkened because of the smoke of the pit. This symbolically means that therefore the light of truth became thick darkness.
The sun and the air here symbolize the light of truth, for the sun symbolizes love, and the light from it, Divine truth. Consequently, when we are told that the sun was darkened, and with it the air, it symbolically means that Divine truth became thick darkness. That this resulted from falsities accompanying lusts is symbolically meant by its being because of the smoke of the pit.
Daniel 10:5-6
5
I lifted up my eyes, and looked, and behold, a man clothed in linen, whose thighs were adorned with pure gold of Uphaz:
6
his body also was like the beryl, and his face as the appearance of lightning, and his eyes as flaming torches, and his arms and his feet like burnished brass, and the voice of his words like the voice of a multitude.
