What you've written reminds me of a scene from Il Postino, when the postman is trying to understand why Neruda writes in metaphors. The whole movie might be a good way to think about myths and metaphor...

Anyway:

You see, Mario...

I can't tell you...

in words different

from those I've used.

When you explain it,

poetry becomes banal.

Better than any explanation...

is the experience of feelings

that poetry can reveal...

to a nature open enough

to understand it.
