Óðsmál (research Iceland) has rediscovered the fundamental physics contained in our delightful symbolic language: Freyja means foam, afros means foam, physics tell us that there is a space-time foam, bubbling, and that one and one bubble breaks lose to become a universe. Some are short-lived, ours is fairly long-lasting.
(I know. These personifications are a trap: the goddess is coming out of her bath.)
During our life-spans in a universe we evolve. We are here to evolve to perfection. Life-span after life-span. Evolution never goes backwards, but forward or stagnates. Let us use our life-spans wisely.
