428. Just as the world of spirits is a state halfway between heaven and hell within us, it is a halfway place. The hells are underneath it and the heavens above it.

All the hells are closed on the side that faces that world, accessible only through holes and crevices like those in rocks and through broad gaps that are guarded to prevent anyone from coming out without permission, which happens in cases of real need, as will be discussed later. Heaven too is bounded on all sides, and the only access to any heavenly community is by a narrow way whose entry is also guarded. These exits and entrances are what are called the doors and gates of hell and heaven in the Word.
