All the literature they publish uses subtle indoctrination techniques to slowly draw you in using what appear in the surface to be good and positive ideas, concepts and teachings. you are led to believe you can find peace, security, happiness, freedom and real future and real love by following and adhering to these concepts and in joining with these people. you are even given a taster and experience of these things on a small scale which serves to convince you that you have indeed made the right decision.
Then they switch the game on you.. with with same subtle brain washing they gradually take over and own outright your conscience and your core being and feelings and definitions of what and who is good.. what is is bad.. what and who is unclean, pure, just, worthy.. ect. They then use the strings and hooks attached to your core being to manipulate, control and coerce you into being and doing what they want.
You are now like a bird caught in a snare. It can take just a year to get ensnared.. but up to 20 or even 30 years to get out again.
That's just how dangerous this cult can be.
