There are plenty of pieces speaking of the desirability of letting go. Especially in eastern thought, speaking of "letting go of worldly desires and earthly attachments," though that's not quite the capitalist mindset most of us are raised in, is it? And then again, in our culture, I guess we could encounter it among narratives of overcoming addictions.

Here is another take to consider (not saying whether this is the intended one, but I like mythical reads on things) - what if you need to go to the underworld to lose a bit of yourself? To prove by trial that you are worthy of the feat?
What if you need to go to the underworld to lose a part of yourself, because afterwards, you must be reborn, without said part?

And I'm glad you liked the piece and the imagery, Moe. I appreciate the comment. It's interesting, but I don't set out to use the mythical imagery, it is just the way the poems come out.

As for the "new perspective," I guess it was something you thought of, but needed help releasing, because what you get out of writing is very much dependent on what you bring into it.
