Perhaps Amemeba meant that words facilitate, like tools, and certainly that is true, but words also have the power to project things otherwise beyond understanding, purposefully and adroitly, in the hands of a poet, but, likely as often, without glamor or glory, by pure happenstance.

Ah yes, grapho, you approach understanding why the words of poetry are necessarily fuzzy. The words of poetry must transend conventional meanings in order to give the reader of the poem ample latitude to adapt the meaning of the poem to suit* his own unique insight into the nature of things.

But first the reader must respect the poet enough to make himself look long and hard for the reader's own particular meaning.

* suit. Used to keep in theme.
