Words Can Only Describe

 Words Are Not Real 

 Words describe

 but are not things 

 in themselves

 except for 

 occasional magic 

 when sound and rhythm 

 combine to make 

 an incantation 

 known as poetry 

An incantation or enchantment is a charm or spell created using words.The term derives from Latin "incantare" (tr.), meaning "to chant (a magical spell) upon," from in- "into, upon" and cantare "to sing".https://en.wikipedia.org/wiki/Incantation 

Considered by many to be the most perfect poem in the English language, Coleridge's poem Kubla Khan sings with its own enchanting music.

 Kubla Khan 

 or  

 A Vision In A Dream 

Samuel Taylor Coleridge

In Xanadu did Kubla Khan 

A stately pleasure-dome decree: 

Where Alph, the sacred river, ran 

Through caverns measureless to man 

   Down to a sunless sea. 

...

...with music loud and long, 

I would build that dome in air, 

That sunny dome! those caves of ice! 

And all who heard should see them there, 

And all should cry, Beware! Beware! 

His flashing eyes, his floating hair! 

Weave a circle round him thrice, 

And close your eyes with holy dread 

For he on honey-dew hath fed, 

And drunk the milk of Paradise.
