This book explains well what causes people to 'snap', and it also explains how snapping is brought about in cult situations.
In addition, the book offers some hope for getting people out of these unethically influenced states of mind in the cases of cults, 'human potential' organisations, and 'self help' seminars.
Many 'human potential' organisations, and 'self help' seminars use similar methods to those employed by cults. Beware. Research them well through the Internet and through people who have done these courses beforehand. Too many sad stories are available on the 'net about the negative influence of such organisations. Not all of them are bad, but do the research beforehand.
Many of these courses promises breakthroughs. Sadly, the moment of breakthrough is often actually the moment of breakdown.
This book will give readers an understanding of sudden personality change and being educated about it is the first step to being able to do something about it if, as in my case, you have had a loved one subjected to these unethical practices.
Believe me, it is a frightening and hurtful experience. For me, it has been going on for a year. For others, sometimes it has gone on for decades.
Also, if you are interested in Jim Jones, Jonestown, and the People's Temple or David Koresh, the Branch Davidians, and the Waco tragedy, this book offers a good breakdown of what happened.
I highly recommend it. It is one of the best books on what happens to people in cults, and other situations that cause sudden personality changes.
