My dad was in the Army when I was little, and I grew up a "military brat". We moved around a lot. I got to see lots of interesting places, but changed schools a lot. It also meant that I was raised with a pretty high opinion of soldiers, the military and a deep respect for the men and women who fight for the freedoms I enjoy every day. When I was little, I wanted to grow up and follow in my father's footsteps, and when given the opportunity, I joined the JROTC in high school. After 4 years, I realized that kind of structure was not something that I was well suited to live with, and I didn't end up walking further down that path.
But I still hold soldiers in high esteem. They sacrifice so much, even when they come home safely...or don't get deployed to a combat zone at all. Being raised in a military family, I understood some of that, from the eyes of the family of a soldier. My father wasn't always home, and while a part of me enjoyed moving to new places, it was always hard socially. Long time friends weren't something I had growing up, and it was hard to keep up long distance relationships when you're in grade school.
To me, it only makes sense to continue to honor the soldiers after they have passed from this life. Einherjar are the dead warriors chosen by Odin to reside in Valhalla and to join him in the battle of Ragnarok. But I also think that the ranks of the Einherjar include other types of people who have passed but were fighters in life.
This is very much my own UPG (unverified personal gnosis....aka my personal beliefs). I feel that what makes someone a fighter isn't so much about dying in battle, but the spirit with which you life your life. A firefighter who risks his life everyday going into burning buildings to save people has that spirit. So does a mother who fights tooth and nail to defend her children...or to care for them when they are sick or injured.
In the US, we have two days to honor our soldiers: Memorial Day and Veteran's Day. Memorial day focus' on the soldiers who have passed on already, while Veteran's day honors those who are still alive (as well as those who have died). Many Norse practitioners celebrate Einherjar day, choosing either Memorial day or Veteran's day to honor the Einherjar and feast in their honor. I love the practice of making this honoring a part of my own traditions, and I actually think doing both is a viable alternative.
I have talked about beloved dead before, and I don't think that celebrating the Einherjar is the same as many of the other feasts and rituals for working with the dead simply because the focus of honoring the Einherjar is on their sacrifice. More than just remembering and honoring them as people, I am honoring the choices they made in life, the things they gave up, to make the lives of those around them better.
I honor the Einherjar as a way of showing my gratitude for all thing things they did. Many of the people I may remember or honor never knew me. They may have been part of a different era, on the other side of the world, or they may have been family. But they all stood up for what they believed in, and that example is one that should be remembered.
