It’s not really any of my business what parts of Herself Sigyn chooses to show individual followers.
Do I sometimes disagree with some people? Yep. I puzzle out why I feel the way I do, and then I move on with my life. It doesn’t threaten my faith in the least.
No one is really an authority on a God but the God Themselves. Especially in a religion like Asatru where we don’t really have any written lore, especially about Sigyn. Sigyn has Her reasons for approaching who She does, and for showing which parts of Herself to show.
