Steph asked: Do you believe in an afterlife?
Depends on your definition of afterlife. I have personal certainty that I am an individual spiritual being who has lived before and will live again. It's like you buy a car and it eventually breaks down and you go buy another one. That is how I view bodies. The body I had last lifetime died, so I got myself another one and when this one dies I'll get another. It's a very simple concept.
Thanks to the auditing I have had, I can easily recall my past lives, so I have a strong personal certainty about this.
Other ideas of what constitutes an afterlife are things like "heaven" and "hell". There is no data in Scientology about those, so an individual can make up his or her own mind about them.
