Scientology is dangerous because it is not a complete lie. It is closely related to the feeling, the knowledge and the ability to act of a conscious being, that is what becomes for humans, feeling, thinking and willing. This helped me in my thinking about science. The four sorts of auditing, for what others have done to you, for you have done to others, what others have done to each other and what you have done to yourself, has helped me to understand what could be the 4 stages of human consciousness, related to the four states of planetary evolution, which have occurred according to Rudolf Steiner. Other examples also exist, which I cannot remember.
More research is needed.
