In Exodus 20:25, this signifies truths formed from good, or good in form, to signifies that nothing of self-intelligence should be involved in its forming. (Apocalypse Explained 391[21, 21])

126. LIGHT AND HEAT IN HEAVEN.

That there is light in the heavens those who think from nature alone cannot comprehend; and yet such is the light in the heavens that it exceeds by many degrees the noon-day light of the world. That light I have often seen, even during the evening and night. At first I wondered when I heard the angels say that the light of this world is little more than a shadow in comparison with the light of heaven; but having seen it I can testify that it is so. The brightness and splendor of the light of heaven are such as cannot be described. All things that I have seen in the heavens have been seen in that light, thus more clearly and distinctly than things in this world.
