That's the way I understand it, too: metaphor, probably a Christian creation to convert the Heathen masses to their path in past, then they could say something like "See, your gods will die, but ours will last forever".
Ragnarök is probably one of the few stories of Norse Heathenry I'm not keen on; I guess I like my eternal life idea too much; I'd rather stay dead or stay 'alive' (for lack of a better term, lol), I guess.
Thanks for the frubal. Google 'natural burial' or 'green burial' for more info. There are woodland areas of the UK dedicated to these type of burials. The more people buried there, the larger the forest grows because of the tree planting over the coffins. What better way to be remembered than being part of a forest!
I've been to Iceland a few times, where Asatru is gaining strength. Have you been to any areas where the Nordic gods are strong? I'm an atheist, but am very interested in nature-based deities and how people translate that into their lives.
