Just about anyone who is involved in disaster relief can benefit from learning about the techniques in the Scientology Handbook.
I've found some people have the misconception that you have to be a Scientologist to by a Scientology Volunteer Ministers or use the techniques. That's absolutely not true.
And I think you will find if you speak to some Scientologists that no one cares what you are as long as you use this technology by L. Ron Hubbard and pass it on to others so they find out about it and use it too.
The only other thing a Scientologist would ask is that you use it as it is written and don't alter it, because Scientology is a precise technology and it works when it is applied exactly.
