I tried and I tried to help friends escape but w/the exception of one my attempts failed. He had experienced a major drip and expressed it to me. I told him I'd tell him what I think if he really wanted to know. He said yes and never attended a cult event again on local or national level. We remain in contact to this day.
Other than that, my attempt to warn other friends turned out to be the big squadoosh. A few are willing to talk on the most superficial level. They even call or email me. Most though, want nothing to do with me. Rather difficult for those who have bought into this crap for 40+ years to have the honest conversation w/themselves.
Some I know seem to embrace Rawat but have done their own spinoff like yoga.
