A person is an immortal spiritual being (termed a thetan) who possesses a mind and a body.
(I'll go along with that)
The thetan has lived through many past lives and will continue to live beyond the death of the body.
Through the Scientology process of "auditing", one can free oneself of "engrams" and "implants" to reach the state of "Clear", and after that, the state of "Operating Thetan". Each state is said to represent recovering the native spiritual abilities of the individual, and to confer dramatic mental and physical benefits.
(Interesting. The word "auditing" usually has a negative connotation)
A person is basically good, but becomes "aberrated" by moments of pain and unconsciousness in his or her life.
What is true for you is what you have observed yourself. No beliefs should be forced as "true" on anyone. Thus, the tenets of Scientology are expected to be tested and seen to either be true or not by Scientology practitioners.
(Ahh, but what if my "tenets" don't match up with yours? Can we still be friends?)
Psychiatry and psychology are evil and abusive practices.
(You just lost me)
They also have a "disconnection" policy, in which members are encouraged to cut off all contact with friends or family members critical of the Church.
(Apparently their beliefs aren't strong enough to withstand scrutiny)
These last two points cause me to conclude that they're rubbish.
What do you guys think?
