You know, the book The Hollow Earth, by Raymond Bernard (pen name) does confuse the hollow portion and the worlds within the crust. It speaks of reaching Shamballa in the hollow earth through the crust. You know, you would have to pass through some layers where the physics of those worlds is completely different, and the creatures. You would have to pass through hellish environments.
Anyway, they are two separate places. The hollow earth is on the surface of the earth. There are humans there. In times past, the Eskimos spoke of receiving eskimo populations from the North, so they myust live at or near the neck on the openiing.
The animals walk in and out when they hibernate. When Olaf and his father sailed in and out, they never left the sirface.
I am sure that the inner crust dwellers have been cultivating a multittude of genetically superior human bings just so that they can take over the surface.
This is where I lean, also - that the north countries are quite possibly in the earth, and they come out of an opening in the north. I'm under the impression that the ice flows down because, otherwise, it would impede their ability to come up out of their country/ies.
@Ephraimite , @SilverMoon , excellent insight about the "Northern countries" referred here - they have to be inside the Earth , the way their location has been described !
@Ephraimite Very interesting stuff. Seems he was extremely clever and was implemented to research and verify specific important information. It would seem likely that his research has an important role and foundation to which the past unfolded.
@Ephraimite , @Echo_on , Max Muller was also the leading European scholar for Sanskrit and Vedic studies during his era...he had delved very deep into those subjects as well !
