"Let there be light!"

Maurice Sapiro, "Red Sunset"

And God Said, "Let there be light!"

Earth heard the loud, the solemn sound, 

And started from her utmost bound, 

And Darkness, on his ebon car, 

Spread his black wings, and fled afar; 

The dun clouds opened with affright, 

And hailed the burst of life and light!

''Tis light! 'tis light!' the mountains rung, 

''Tis light! 'tis light!' the valleys sung! 

The stars beheld its dawning bright, 

The spheres confessed the Godhead's might, 

While Nature's universal voice 

Proclaimed aloud, 'Rejoice! rejoice!' 

Charles Mackay

If I'm going to be adding "Let" poems, for sure I have to include the biggest one. If I think about it, "let" was the first word ever recorded. The first word. No wonder it strikes me. Here, it is the word that brought about the birth of the universe, of being, of awareness, of life. The supremely beautiful word of creation.
