So, to trigger something like that state deliberately, here are rules of the game. This is for fun, not literary glory, but give it some care anyway.
1. Close eyes tightly (no cheating) and approach bookshelves.
2. Run hands quickly over book spines and pull out one book.
3. Eyes still shut, put book down and open at random, placing finger anywhere on page.
4. Open eyes and take one sentence from the place marked by finger.
5. That is the opening sentence of your poem, which must rhyme, and must be completed the same day, preferably the same hour.
6. When finished, give the title of the book you got the sentence from.
7. If you wish, post the poem here, and/or on your blog and/or FaceBook.
Here's my first one - guess what book the first line is from? (answer is below)
FOR THAT WRONG COMMITTED MUST YOU KNOCK
the shit out of that wrong old block?
Listen here mister prophet
from your wisdom I cannot profit.
I'm the chip off that old block of wrongs
and out of it I make these songs.
(The first sentence is from Khalil Gibran's The Prophet)
