The first time you suck the glass dick and get that one hit that get you so high off crack you never get that high again on crack. It is the closest you can get to god without taking LSD.
Raekwon's pyrex vision,
"The rise came upon me"
He talking about the Rise of God and how crack keep you fiending for days. It's followed by chasing the rock. As long as you live, you can never get as high off crack as you do that first hit. Yahzeeme?
