White Box Reincarnate

The religion/belief that after you die, you will be reincarnated into a lowlife cockroach and if you lived nicely to the ones around you (as a cockroach), you will move up in the animal food chain (living each life nicely) until you slowly move back up to human status. Once you lived your lives without committing horrible acts, you will wake up into a white box, neither cold nor warm.

Person 1: So what religion are you?
Person 2: I'm a White Box Reincarnate.
Person 1: Why?
Person 2: Because I want to believe in an afterlife.
