Scott Carney wrote a long piece for Details about “India Syndrome” — one of may place specific menal disorders (see Wired’s coverage of Jerusalem Syndrome, which mentions that the majority of people dealing with these syndromes have pre-existing psychiatric issues).

But particularly interesting is a bit about the potential negative sides of meditation (something that we’ve discussed here before):

Less discussed are the disorienting and damaging side effects of meditation. Neophytes have reported seeing walls move or rooms change color. The introspective state that is one of the goals of meditation can induce feelings of paranoia and terror. According to Willoughby Britton, a neuroscientist at Brown University who studies the effects of meditation on the brain, practitioners can perceive small sounds as cacophonies and lose the sense that they are in control of their own actions. Britton has claimed that this experience, which some refer to as the “dark night,” has caused numerous people to wind up on psych wards under suicide watch. Guided visualizations… 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.”
