Arcana Coelestia #9
9. The third state is one of repentance, a state in which he speaks piously and devoutly from the internal man and brings forth goods, like charitable acts which are nevertheless inanimate since he imagines that they originate in himself.

Arcana Coelestia #1619
1619. THE LIGHT IN WHICH ANGELS ARE LIVING - continued; ALSO THEIR PARADISE GARDENS, AND THEIR DWELLING - PLACES
When a person's interior sight - the sight of his spirit - is opened, he then sees things in the next life, things that can never be manifested before his bodily eyes. The visions that the prophets had were nothing else. As has been stated, representatives of the Lord and of His kingdom, as well as meaningful signs, are to be seen constantly, so much so that nothing ever comes before the eyes of angels that is not a representative or a meaningful sign. This is the origin of representatives and of meaningful signs in the Word, for the Word derives from the Lord through heaven.
