The New York Times of Sunday, March 7th (hard copy edition) had an interesting front page article about exiting and exposing Scientology.
Those who left the Transcendental Meditation Movement after working close to inner core activities probably can relate to Scientology tactics in this article... abysmally low wages, expensive advanced courses, repression of bad outcomes, promotion, protection & catering to celebrity participants, intimidation tactics about departure & about publicly disclosing inner 'secrets', rejection from so-called loved ones after speaking doubts about cult teachings or departing, difficulty integrating to the outside world.
For those interested, this link brings you to the online article:
