Zetsu's final message: Hey, Buddhists, you guys are screwed. Even if you reincarnate, the world's gonna be exploded, so you will be reincarnating into empty space and just die, then reincarnate, living only seconds each time, and be trapped in a perpetual cycle of reincarnation in which you can never achieve Nirvana because you've only got enough time to wonder: "Hey, why the hell aint' my lungs/gills working... Oh shi-" before you suffocate in the vacuum of space.
