This fascinating legend of a man, Leeland Conrad Powers, mad with a want of freedom, who imprisons himself in a string of faulty lies; depleting his sense of stability and spiraling him, thoroughly, into madness and obsession is well worth watching. Intense, loosely edited, but nonetheless compelling, direct and honest tale of how Satanism mixed with psychotherapeutic hypotheses based in hypnosis can, theoretically, lead to a cult of Charles Manson Family proportions and eventually a religion like Judaism, or Scientology. No offense intended, just examples.
Powers' followers are hypnotized into believing that all physical phenomenae are just processes of the mind, and not actually occurring. They avoid psychology and hypnosis ideas, and those in-the-know about them, because they are the basis of SciMIND, Powers' name for his process, and would easily discredit him as a quack, brainwashing people. The main tenet of Scientific Spiritualism, the religion, is that followers give it money... though they are a nonprofit organization.
Ironically, Powers' madness leads him to believe his own ball of hooey, and he takes himself to be a true prophet of God, though he started it all to escape the fate of imprisonment.
This is well worth watching. And, because the movie's distributor is not allowed to profit from sales in the United States, I think that you can make as many copies as you want in that country and give them away for free.
