try this for size

here's a light write one high night

days gone past
tomorrow will forever last.
down among the trodden caste
i stand the spell time has cast.

on a dawn of aching hours
time takes the stars down
prohibiting twin towers,
showing that life is descending sound.
but laughter sparks the burn
to face the everlasting yearn
at last, to place the stern
among the confines of an urn.

maybe not so "light"

i enjoyed this peice but i was caught off guard by the tempo change. If i may make a suggestion. in the first stanza you have a rhyme on lines one and two but you have a metered rhyme that is also a play on words in lines 3 and 4. as far as structurally i just kinda skipped the first part. so perhaps if you reworded it and placed it at the end. so that rhyming double beat and entendre would flow better.

Other than that your imagery is wonderful. Your using some wonderfully powerful images that evokes meta feeling which i always find fascinating and fun to read. thanks for sharing, im looking forward to seeing more of your work

cool thanks. i appreciate that, i have other shit that has gone through many stages of editing. but it always needs more
