35. Because of this distinction an angel of one heaven cannot go among the angels of another heaven, that is, no one can ascend from a lower heaven and no one can descend from a higher heaven. One ascending from a lower heaven is seized with a distress even to anguish, and is unable to see those who are there, still less to talk with them; while one descending from a higher heaven is deprived of his wisdom, stammers in his speech, and is in despair. There were some from the outmost heaven who had not yet been taught that the interiors of angels are what constitute heaven, and who believed that they might come into a higher heavenly happiness by simply gaining access to a heaven where higher angels are. These were permitted to enter among such angels. But when they were there they could see no one, however much they searched, although there was a great multitude present; for the interiors of the newcomers not having been opened in the same degree as the interiors of the angels there, their sight was not so opened. Presently they were seized with such anguish of heart that they scarcely knew whether they were alive or not. Therefore they hastily betook themselves to the heaven from which they came, glad to get back among their like, and pledging themselves that they would no longer covet higher things than were in agreement with their life. Again, I have seen some let down from a higher heaven; and these were deprived of their wisdom until they no longer knew what their own heaven was. It is otherwise when, as is often done, angels are raised up by the Lord out of a lower heaven into a higher that they may behold its glory; for then they are prepared beforehand, and are encompassed by intermediate angels, through whom they have communication with those they come among. From all this it is plain that the three heavens are entirely distinct from each other.
