2208. While I was walking along the road, an angel attempted to see how the properties of an angel flowed into an earthly human, and thus to investigate the interactions. But he did not succeed except in a few respects. The reason, I realized, was that the thoughts of angels, though richer than man's thought, were too tiny to arouse interactions. And besides, things of his own were getting mixed in, and thus evil feelings, which were being stirred up. Moreover, these feelings are of a cruder quality, and when they stirred them often enough, they also aroused a mixture in the person's mind, letting spirits grasp the opportunity to raise up disharmonious mental imagery. In short, angels' mental imagery is extremely limited, and cannot possibly lead a person on earth; but to the extent that it comes from what is the angel's own, it would corrupt the person. 1748, 6 June.
