You've Got To Be Kidding Me...REALLY!
There's so much I want to say about this movie (though at times I suspect it's a joke being played on the viewer). Sure, I could make a dozen jokes about the participants in this "workshop" but I'll do my best to restrain myself.
The history of mankind is littered with con artists; some promote un-burdening yourself of worldly possessions and demand you sign away your assets. In this pervert's case, he asks his attendees to indulge in group sex in order to find themselves spiritually. In some cases, it can be very dangerous. Think Jim Jones of the People's Temple in Guyana who followed a false prophet as they signed away their possessions and ultimately their lives.
Much in this movie (and life, too) is said about man's (or woman's) natural state or condition. That monogamy is not natural. I would agree with that but so what? Does that make a life of multiple sexual partners a healthy and fulfilling life?
Impulse is mankind's natural state; doing what feels good. This includes having sex non stop with everyone possible, consuming unhealthy food and never-ending leisure activity. Obviously, living a life of impulse will lead to the collapse of civilization.
The only person profiting from this workshop is the guru, his bank account and all the crabs that found a new home.
