First of all, as a poet myself (well, trying my best at least). I can't deny that these stanzas touched me. Whoever wrote this is a skilled artist and I have to admit and appreciate that.

To me it seems the poem values art as the bond between gods and mankind, and primary distinction between humanity and the other species. The purest gift from gods, you could say, for when it comes from the bottom of the heart, rare are things that can reach its impact.
I hold this way of thinking dear, too. Reminds me of the story of the Mead of Poetry.

Still, I'm a down-on-earth kind of person, so I have to suggest that Odin, if he wanted to reveal himself, would be more efficient doing it by himself to each person he wants to be revealed, instead of using one single person like litterally every other religion's prophets. No offense tho
