5219. And behold it was a dream. That this signifies in that obscurity, is evident from the signification of a "dream," as being an obscure state (n. 1838, 2514, 2528, 5210). It is called "obscure," because truths had been banished; for where truths are not there is obscurity, because the light of heaven flows only into truths; for the light of heaven is Divine truth from the Lord. Hence the truths with angels and spirits, and also with men, are subsidiary lights; but they have their light from the Divine truth by means of the good in the truths; for unless truths are from good, that is unless they have good in them, they cannot receive any light from the Divine. They receive it by means of good, for good is like fire or flame, and truths are like the rays of light from it. In the other life truths without good do indeed shine, but they shine with a wintry light, that in the light of heaven is thick darkness. From this it is evident that what is here meant by "obscure," is the state of the natural when the good memory-knowledges had been banished by those of no use. An obscurity like this can be enlightened in a general manner (n. 5208, 5218), but by no means can that obscurity which comes from falsities; for falsities are so many darknesses that shut out the light of heaven, and thus cause an obscurity that cannot be enlightened until the falsities have been removed.
