@sozobe,
Yeah...I certainly came across lots of people who were in various of these things...Ananda Margha is one that comes to mind, as a beloved shared a house with one of them.
It's odd, because I would see my then self as highly susceptible to cult recruitment, but I always felt very creeped out by them, all of them.
I think it was the happiness thing....you know, peace, love and brown rice and lots of smiles and eternal warmth.
It made me want to run.
