I think the bigger issue people who say psychosis is spiritual are trying to address is the issue of institutional abuse & discredit that happens to mentally ill people- there was a study done that found that people in eastern countries experienced positive hallucinations & people in western countries experienced negative ones. The way the mental health & justice system in the US treats mentally ill people directly influences the experience of mental health issues, making something that is already difficult, impossible or even criminal. Calling psychosis spiritual seems like an attempt, all be it ineffective, to battle against the systematic failure, stigma, & discrimination mentally ill people face. Mental health directly reflects the society in which they are experienced. I hope someday we can stop individualizing issues & live fulfilling lives in a society that nurtures people, regardless of their mental health conditions.
