Part of the major problem attending schizophrenia is what it is defined to be, that is, abnormal, rather than an altered state of consciousness that has a specific ecological function for the species. In the West, such states are labeled as an illness and are almost always medicated. Most psychoactive drug use is proscribed for exactly the same reason . . . you must not extend perception further than the society wants it to go. There are very few people in the West (and virtually none who are clinically schooled) who understand how to train someone in the use of that enhanced perception. Once such gating dynamics are labeled abnormal, accepted to be neuropathological, there is generally no alternative (in that system) except pharmaceutical suppression.
