On top of that, I was reading into Buddhism yesterday, because of his lyrics and talk about liberation, karma, rebirth and consumption of things. Many of the things in the album fall in line with many Buddhist ideals about the cycle of rebirth. He's always been indirectly known as an atheist, so this religious attitude seems very recent.
