A passage from Arcana Coelestia ~ Emanuel Swedenborg
The internal sense of the Word is especially for the angels; and therefore is adapted to their perceptions and thoughts. They are in their delightful, nay, in their blessed and happy states, when they are thinking about the Lord, His Divine and His Human, and how the Human was made Divine; for they are encompassed with a celestial and spiritual sphere which is full of the Lord; so that it may be said that they are in the Lord. Hence nothing is more blessed and happy to them than to think in accordance with the things that belong to that sphere and its derivative affection.At the same time, moreover, they are instructed and perfected, especially in this:
How the Lord by degrees and of His own power, as He grew up, made Divine the human into which He was born; and thus how, by means of the knowledges that He revealed to Himself He perfected His rational, dispersed by successive steps its shadows, and introduced it into Divine light.These and innumerable other things are presented before the angels in a celestial and spiritual manner, with a thousand and a thousand representatives, in the light of life, when the Word is being read.
But these things, which are so precious to the angels, are to men as of no importance, because above their comprehension, and thus in the shade of their understanding; and on the other hand, the things that are precious to men, such as those which contain within them worldly matters, are of no importance to the angels, because below their state and thus in the shade of their wisdom. Thus, wonderful to say, the things that come to shade with man, and almost into contempt, with the angels pass into light, and into their affection, as is the case with many things of the internal sense of the Word.
