Well I think that’s a bit of a straw man. Who’s to say that these teachers do not have training in traditions that have essentially evolved their own treatment modality for psychiatric ailments. Just because they don’t have formal training doesn’t mean the cultural traditions don’t have effective treatment for meditation-induced psychosis. Sure maybe Goenka and his school may be an isolated case where such training wasn’t provided (hence the need for an advanced master) that’s not to say there aren’t examples of masters (several of whom I’ve witnessed personally) that are able to handle the psychotic imbalance that arises from pursuit of these advanced practices.
