Just an interesting observation of info I have come across lately:
Lately, I've read about a young happy woman that went to a Yoga class, and became involved in a cult. She could not believe it. What did the cult leader use? Emotions.
One book about cults describes how cult lealders manipulate emotions, and make their followers slaves to them. (Sorry I don't have the names of books or links... just too tired tonight)
It all starts out happy "release bad feellings" "shout happy ones" and then the next thing you know, little by little, you are part of a cult.
They know what they are doing, the pattern works.
(PS, I like emotions... they all have their place)
