1) To get a take on how the leader might have gotten started (this is just a hunch), get and read 'Prophetic Charisma' by Len Oakes, who is a clinical psychologist and researcher in Australia.
Dr. Oakes was once in a group led by a charismatic leader and if you can locate him (use Google) he may be able to offer you some pointers. His book may help you de-mystify the leader.
Another book, by Amy Wallace, describes her life in a secretive group centered on Carlos Castaneda, entitled 'The Sorcerer's Apprentice.' Its a painful book to read in places, so if youre feeling fragile, either wait or make very sure you have some supportive friends. The reason I recommend the book is it gives brilliant descriptions of two features of the group: people were selectively recruited. And once you were in the group, you were forbidden to ask questions.
Forbidding people or shaming people for asking questions puts them in a very difficult position.
When you're forbidden or shamed for asking questions, you're likely to feel anxious and off-balance much of the time, and you constantly scan the leader, senior members and environment for cues so you will know how to do the right thing--not do something that would result in a scolding or worse.
To be forbidden to ask questions shifts the power dynamic to favor the leader and dis-empowers the members.
Life within a group like this can feel deliciously intense. Giving up that sense of intensity, the promise of power and that feeling of being special --its painful to walk away from. And you lose the easy comraderie of people in the group.
In case this helps, here is an interview describing how someone left another group that specialized in energy work--in this case they called it 'Siddhis'. In this case, the person felt he'd benefitted from psychotherapy, but acknowledges that others may not find this necessary.

Possibly a Codependants Anonymous 12 step meeting could be a helpful resource, as well. The 12 step model is non-authoritarian and a very good contrast to an authoritarian group. Even if you go to such a group for just a brief time, you will be able to see that there are ways to form a group that will not go in an authoritarian direction.
