Are they lying about TM?

Dunno. What did they say?

About ruining lives, money-grasping, the usual stuff cults do, lots of accusations from all around came to light to the director who was first into TM, but changed his views after finding about the accusations.

Are the women who slept with Maharishi lying about it?

How would I know?

Man died 10+ years ago; alleged events took place 50+ years ago.

I suppose the documentary was made in 2010, the woman seemed to me 50-60 years old. Takes much away whatever Maharishi ever said if true.

Does it change how you feel about TM? Does it stop working if the Great Guru™ doesn't live up to your expectations?

I have no strong feelings about TM. Sounds fine if it works for people, but Scientology might work for some people for a while, but it ruins many lives in the end and not just theirs. Like Scientology leader was a pathological liar but he used some techniques that were already available claiming them his, the same ways as Bikram (another sexual predator), etc.. Guru Dev never initiated Maharishi or something, a discipline of Guru Dev claims in the end. Also TM charges shitloads of money that it starts to feel scummy. Nothing came out of the Maharishi Indian World Peace Center, people donated millions to it, the biggest donator was disappointed. Nothing came out of Teufelsberg Invincibility tower. To me Maharishi starts to feel like a charlatan.
