Enginn má sköpun renna
no-one can run away from his (self-made) örlög (fate)
Urður Verðandi Skuld are just physics.
Óðsmál tells us that there is hidden profundity in myths and sacred poems in our Eddas.
* Urður is our doings, * Skuld what we get back, as an action always has an equal reaction (physics). Skuld means a debt, and is related to skylda (duty). Fjölskylda means family, and we even have chosen that part.
In the Bhagavad Gita part of Mahabharata, says: The ways of actions are unfathomable (gahana karmano gatih). Karman means action. Do not even try to understand returning actions/karma. Their ways, * Verðandi, are too complicated.
