"...the Eckankar writings are riddled with fear tactics right out of Scientology and dire threats of what damnation awaits anyone foolish enough to quit. Without the Living Eck Master's guidance, all a person's karma is dumped onto his head and will likely crush the poor soul. Numerous threats promise countless rounds of more miserable lives spent in the astral hells and back here on earth. All is not lost, though, if the hapless student someday crawls back to the feet of the Living Eck Master and asks to be saved. As you may guess, these fear-laden admonitions against quitting are only available to the student after approximately 10 years of conditioning (er...study), so new members have absolutely no idea what less-than-pleasant surprises await them down the road."
When I first quit, I was a bit worried about what would happen next, but I was willing to take the chance because the whole movement seemed such utter bullshit. They claimed stuff like every famous person who ever lived was secretly an Eckist and/or an Eck Master.
From my experience, I think cults are most effective on the young, on persons who have recently been traumatized and need something to fill the void, or people who desperately need the approval of a group to belong to.
When I joined Eck, I guess it was a youthful indescretion and it seemed like a good idea at the time.
