A Riddle Unsolved

Something novel:
a good augury?
creeping to augment,
an esoteric fall.

I repeat the mistake of knowing too much.

Submodified. The man?
still wants to bite the tongue
on the name of truth.

It was very unpleasant
to see a hummingbird
becoming a sphinx.

No need to commit a suicide after homing,
to a blazing icon in the urn.
