Dr Hew Len worked in a psychiatric hospital for the criminally insane for 3 years. He was faced with a host of rapists killers; all were extremely violent people. It was truly was a mad house with seemingly impossible problems in every area, staff quitting, housing, fighting, maintenance was poor, moral was terrible and the patients never left. They were often hand cuffed and bound to keep them out of trouble and under some sort of control.
Dr Hew Len never saw his patients in a therapy session in or out of his office. Instead he would retreat to his office and look at one patient's file. He would do Ho'oponopono. In time, 3 years later all the patients were released because they were no longer a threat to themselves or society. The hospital was eventually closed.
