Inside a Church of Scientology
It's amazing what this video covers in four minutes. I think it will answer a lot of questions that people have.
If you have any other questions then check out other videos at Scientology Video Channel on YouTube. You can select videos from the fancy menu or you can see them all listed here: All Scientology Videos on YouTube.
If you still have questions then ask me: I will answer your questions about Scientology (I sometimes take a few days so be patient.)
