6313. When a man is being elevated toward interior things, he comes out of the gross sensuous light into a milder light, and at the same time is withdrawn from the influx of scandalous and filthy things, and is brought nearer to the things that belong to what is just and fair, because nearer to the angels who are with him, thus nearer to the light of heaven. This elevation from sensuous things was known to the ancients, even to the Gentiles, and therefore when the lower mind is withdrawn from sensuous things, their wise men said that it comes into interior light, and at the same time into a tranquil state, and into a kind of heavenly bliss; and from this they also concluded that the mind is immortal. Man is capable of being elevated still more interiorly, and the more interiorly he is elevated, the clearer is the light into which he comes; and at last he comes into the light of heaven, which light is nothing else than wisdom and intelligence from the Lord. The three heavens are distinguished in no other way than according to elevations toward interior things, thus also according to degrees of light; the third heaven, being in inmost things, is in the greatest light, thus in a wisdom which far surpasses the wisdom of the lower heavens.
