Great Poetry?

How could anyone ever truly Define great poetry? Factors are so many that contribute To the way each person does hear-feel-and see. The season, the day, the very time, Along with each readers wisdom-knowledge-and mind. A line read one day May deeply stir the spirit While the very next time read The reader simply just can't 'get-it'. Besides, who is to judge, And who is to decide? Who always speaks truth, And who pray tell has never lied? Let the one who has never struggled with emotion and word Cast the first critical stone, Let the pure, perfect poet Read and write completely all alone; Enshrined by himself Upon his own empty throne. After all, it is supposed to be A bit (or more) of myth and mystery, A little difficult to decipher, somewhat vague, Meant to speak, but not brag. For Goodness sake, it's poetry. Not prose, not essay, and certainly not the news. It's forms are many and free, It's thoughts different and deep, It's direction everywhere the heart can see, It's origin, and destination, ineffable... But to write, one must try, or die... such is the poems strength. So, let the creator of words create. With wild and wonderful words to decipher and debate; And never let the beauty of it all In trivial criticism suffocate. What is great poetry though you still inquire? I should have told you from the start; (But, then you would not have listened) Great poetry is always, and only, Beautiful words written truly From, and for, the heart.
