The thetan has to report to a “between-lives” area, Hubbard later explained, which for most of them is the planet Mars. There the thetan is given a “forgetter implant.” “The implant is very interesting,” Hubbard later wrote. “The preclear is seated before a wheel which contains numbers of pictures. As the wheel turns, these pictures go away from him.… The whole effect is to give him the impression that he has no past life.” The thetan is then sent back to Earth to pick up a baby’s body as soon as it is born.
