The Doctor who tried this method is Dr. Hew Len, Hawaiian Native. He cured the people from a mental facility in Hawaii and the mental hospital eventually shut down..
It is not exactly what I heard. It was a prison, with an area for mentally ill hardened criminals where nobody wanted to work because the inmates were so dangerous. With this mantra he healed all the inmates from their mental pain, and they were eventually able to return to the main area of the prison and they closed that special maximum security area.
