Pain is the master of the Six Paths.
The Six Paths is a Buddhistic belief, when a someone dies, he reincarnates into one of the 6 paths, god, demigod, human, demon, animal, and hungry ghost, based on their actions when they were alive (yes, gods die too). Only those who transcend their impurity become enlightened, and rebirth as Buddha of the seventh path, the outer path.
