You're insane Al...
This is how I think it goes:
You start at level 1.
Level 2: Pay
Level 3: Pay even more
Level 4: Get another person to join Scientology
Level 5: Get even more people to join
Level 6: Hmm... Become famous and advertise?
Level 7: Dunno
Level 8: Dunno
Level 9: Get rid of all unhappyness
Rest I dunno.
Level 8 is also called the "Wall of Fire" or something. Only when you're completely happy, you can cross it... Noone has ever done so, I think, maybe except for creator.
