The essence of Scientology's workability is something that each
individual must decide for him or herself. The subject is so large and
could be approached in so many ways (e.g. as an administrator, as an
artist, as an teacher, etc.) that there are literally as many answers to
that question as there are individuals in Scientology.
For Chip: "It is the fact that Scientology offers the only game where
everybody wins. The auditor wins when she or he applies the technology
correctly and sees the preclear get gains. The preclear gets those gains
and comes back for more. The staff see this happening every day and know
that they are helping it happen. The course supervisors know that their
students will be going out and auditing others. You could say that
Scientology's workability lies in the truth of its teachings and the
basic honesty of man. For if man were not innately good, he would never
desire to help his fellow man by committing the time and resources to
train and audit others."
For Brian: "The principles and concepts in Scientology can sometimes
appear foreign at first glance, but once they are understood in their
simplicity (just as one has to understand the simplicity of geometry
before the complexity of algebra, trigonometry and calculus can be
mastered) their breadth of clarification and application becomes visible.
I use Scientology every day, in almost every situation in life. I use it
to help others, often by helping them recognize and clarify situations
which are confusing to them. I use it when I try to explain myself in
ordinary conversation, or when I try to teach or learn a new subject.
Scientology's 'workability', to me, is dependent on how comfortable and
natural one feels with the subject."
