Thank you! I had so far stayed somewhat away from emphasizing "immortality" or "everlasting life" in my thinking about/prayers to Idun, despite the prominence of the apples in the one full myth we have about her. I had stayed away from it because it seems like too much attachment to the eternal life of this here body and its personality tends to go to some bad places, even if ostensibly in a spiritual/religious context.

After further meditation, reflection, and drafting, though, I do think the emphasis is appropriate, if understood as something closer to the "One Life", or the "life of the soul," as I think that's the kind of "everlasting life" it's healthy and desirable to think about and focus on.
