Yes, definitely this. And even before the asana and pranayama (breathing practice) are the yamas and niyamas (yama-niyama-asana-pranayama-pratyahara-dhyana-dharana-samadhi) there are eight rungs to the entire eastern yogic/meditative practice. The whole focus on "meditation" and physical poses by the modern western approach of $50/hr yoga classes completely goes against the eastern method of guru and disciple. There's a reason these things are meant to be studied under a learned master. What's the saying... a little knowledge is a dangerous thing. These practices were studied by students for years before they attempted what some people do in their first couple of yoga classes.. That said, I don't mean to discount the experiences of the individuals described in the article. I think it's terribly unfortunate that anyone has to suffer from practicing meditation and yoga, and also find it sad that they were unable to find a master to help them recover from their experiences sooner.
