Way back in 1974 I got a very strange handwritten letter from someone encouraging me to join Scientology. I did not know them and I do not know how they got my name. Even more oddly, they were in another country. I knew a bit about handwriting analysis (graphology) and the writing was very scatterbrained. It did not seem impressive.
4 years later I walked into a Scientology branch out of curiosity, and the person there tried to convince me that I needed to go through their programme which involved the outlay of money. All I had financially was what I needed for my own survival, so that was not on. Since then I have been watching Scientology like a hawk. I cannot see how Scientology makes the world a better place by taking money from people and enslaving them.
In Christianity there is a sin called Simony, which is where you attempt to sell spiritual favours for money. Many preachers, gurus, and spiritual organisations are guilty of this.
To quote 1 Corinthians 9:7, "Each of you must give as you have made up your mind, not reluctantly or under compulsion, for God loves a cheerful giver".
Speaking of Primal Therapy, I read the Primal Scream by Dr. Arthur Janov in 1979. The neo-Freudianism was excellent, however I knew I had to be careful using it in casual conversation, especially in places where alcohol is served. Some people could be righteously very offended to the point of them engaging in violence towards me.
You have to pay a lot of money to become a Primal therapist, however the economic model is flawed. Janov himself wrote a sequel to the Primal Scream (20 years on) and mentioned that economic weakness. Some Primal therapists have made cults, however I do not know if that is what Janov would have intended. Not only is it prone to being a cult, but there is a high burnout rate among primal therapists. Indeed, you get so much stuff dumped on you by patients if you are doing your job correctly that you cannot last more than a few weeks.
Primal therapy seems to be a bit like Marxism. The critique of the (most extreme form of the) present state of affairs is excellent, but the solutions offered will often lead to totalitarianism, or in the case of the material covered on this forum, cultishness.
