It purports to be a kamikaze chant, and appears near the end of the book. Being basically a Gravity's Rainbow nerd, I have always wanted to be able to write it out in order to impress other literary geeks. It goes:
Hi wa Ri ni katazu, Ri wa Ho ni katazu, Ho wa Ken ni katazu, Ken wa Ten ni katazu.
I can't make out enough of its kanji to find a match using Google, but if it's any help, it means: Injustice can not conquer principle, Principle can not conquer law, Law can not conquer power, Power cannot conquer heaven.
