Thanks to Dobby Gibson and Dean Young I'm currently reading Japanese Death Poems: Written by Zen Monks and Haiku Poets on the Verge of Death. And while I'm not on the verge of death--at least I hope not--if I were on such a verge right this moment, I'd write this:
Two men cutting old limbs
off my tree. One last listen
to KISS DESTROYER!
(Then I'd die immediately, of course.)
What would your death poem be...right this second?
