Do I believe in the Norse myths? As in the Norse creation, warriors going to Valhalla, and the Ragnarok?
I don't know.
However, if you are asking if I feel a connection to the nature and the Gods my ancestors worshiped then yes, maybe not in the truest form but yes. I choose to represent my spirit with the symbols of the Norse, as I have Scandinavian ancestors, even if the gods I feel connected with are not those that go by the names Thor, Odin, Frigg, etc. The names do not matter to me, it is the spirits/gods themselves that matter and how I idenitify with them.
