I enjoyed what a shaman sees in a mental hospital with regards to treating schizophrenic symptoms.

Read the myth of mental illness by Thomas szasz if you really want to realise what a joke psychiatry is,and yes I agree that that they exclude the spiritual completely which is problematic because the cause is spiritual.
hippocrates started the idea that it was a bodily malfunction prior to that everyone knew it was a spiritual issue,or awakening most outside the west still do and because of that they have much higher recovery rates for schizophrenia than the west.
