Thinking more about my earlier post
Valhalla is within you, and the ideas of both Kerning/Krebs and Immanuel Kant that not only is the "Kingdom of God" within you, but also Hell, I have been meditating on the idea that the mansion of the father has many rooms.
This can be looked at from different directions. On the one hand, the many rooms could indicate many individuals who each are carrying their own room in the mansion of the father - i.e. their own individual heaven (and hell). On the other hand, it could indicate that their are many rooms or "realms" within an individual. That is, not only in the "Kingdom of God" and Hell within you, but also all the realms of all the virtues and vices. (This also brings to mind Robert Heinlein's novel
Job and its underlying premise that each individual faces the afterlife they believed in during their life.) On the third hand, you could argue for each room being a lifetime and the lessons that lifetime is meant to teach you.
Taking the second option, the idea of
Valhalla is within you could fit into this, but so too could the third option fit into this Valhalla. That is, each day of fighting in Valhalla represents a lifetime in the physical world. The feasting afterwards represents the time between lifetimes. The people who went to Hel (not the Christian Hell, but the heathen round of Hel where people who did not die nobly in battle went) could be seen as people who were directed to a different set of virtues in their life - the virtues that would be needed after Ragnarok.
Note that this approach to Christian literature is not Christian in the sense of worshiping Christ as
the son of God, but rather Christian in the sense of drawing from the teachings and life of Christ (a more Odinic approach of emulation over adoration), who in my view was
a son of God, in the same way that we are all children of God, where God to me is the divine spirit within us.
