What is Body thetan?
{{unsourced|date=September 2024}} In [[Scientology]], '''body thetans''' are [[immortal]] [[spirit]]s of [[alien]]s [[kill]]ed by [[Xenu]] which put themselves inside the bodies of [[human]]s and cause them bad [[emotion]]s and [[mental illness]]. Scientologists believe that people who finish training in the last levels of [[Scientology]] can use [[telepathy]] to help other people get rid of their body thetans and become [[happy]].
