Sacred Scripture # 34
34. It would be the same for the heavens where angels live if it were not for the world where we live. We, as human beings, are their foundation, container, and support, and we have the Word with us and in us.
Overall, the heavens are divided into two kingdoms, which are called the heavenly kingdom and the spiritual kingdom. These two kingdoms are founded upon the earthly kingdom where we live. A similar structure exists in the Word, which we have with us and in us.
See Heaven and Hell 20-28 on the division of the angelic heavens into two kingdoms, a heavenly one and a spiritual one.
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.
