I think the article may somewhat overemphasize the change in locale (though my old ethnography prof would tell me never to underestimate that) and de-emphasize the easily dangerous effects of breathing and meditation techniques.
I especially noted this part:
These meditation techniques are "designed to completely psychologically rearrange you," says Paul Hackett, a lecturer in classical Tibetan at Columbia University. In a foreign setting, that kind of experience can be even more traumatizing, especially when you take into account the way some Westerners in India tend to snack at the country's spiritual smorgasbord—a little Ashtanga yoga here, some Vipassana meditation there. "People are mixing and matching religious systems like Legos," Hackett says. "It is no surprise that people go insane."Indeed. I think this strikes at what I was trying to get at years ago when talking about the WASP girl with the last name Smith who just got home from the latest Sex and the City movie, having listened to K-LOVE on the drive home, with prayer rope on her wrist, and books by some Athonite elder and Gabriel Garcia Marquez and Kahlil Gibran next to her bed. Not that some absolutist hegemony of interests and entertainments is desirable (or healthy), but that the spiritual smorgasbord you can get in America is also (grant it to a lesser degree than what we read of in the linked to article) going to pull a person in a number of different directions, and this can really, to put it in the language of kids these days, fuck you up. But of course the real analogy is with those spiritual addicts we've all met who, with furious urgency, go from one spiritual experience to another, spiritually high as a kite initially at each one. I've seen more than a few monkabees with the same look in their eyes as seen in that photo of Jonathan Spollen "3 months ago." It strikes me that one indicator of "sanity" in a religious institution is not having many gurus who lead these poor souls on, and trying to make impotent the gurus that they inevitably have. [Where you have clergy in any number, you will have people who think and/or intuit themselves to be gurus.]
Gurus are always a bad idea, worse is the desire to become one. Or, if I might borrow the language of Arturo and Delegado Cero, there is no spiritual vanguard either.
