Is faith enough?
You believe in heaven, you go to heaven. You believe in reincarnation, you get reincarnated. You believe that your consciousness joins other consciousnesses and in one big conscious get together. Or if you believe, nothing happens. Or you go to Valhalla or a spaceship in the sky or whatever, or your good deeds, bad deeds, whatever your belief is, that's where you end up. Again, great. No harm, no foul. Fantastic. But what if it does matter what you believe?
