Awake and at war 'til I'm resting in peace
“Awake” = A/wake — Jocyean!
The meaning continues that of the lines that precede it — Lupe rededicates himself to struggle on behalf of the ghetto, and in particular on behalf of those who have died (“deceased…a wake”) amidst its violence and squalor.
Also, Lupe is awake or enlightened to the state of hip hop. While “at war” with the notion that he has to dumb it down and conform. All this until he finds peace with himself
There’s also a nice bit of dichonimous wordplay in this line — live in war, die in peace.
