Organisms use psychological programs to manipulate the physiological activities of the body to accomplish certain tasks. For example, when a person encounters a dangerous animal in the wild, he will start to run a psychological program to make the adrenal glands secrete hormones and make the muscles tense in order to flee or fight.
Because all of our mental activities run psychological programs to control the body’s physiology to complete tasks (including consciously and unconsciously starting and running them), if an inappropriate program is used, errors occur in a program, or a program is used inappropriately, it will be physically confusing or ill effects will show, such as tension headaches, convulsions, mania, and hallucinations. These physiological reactions will bring pain to the living body, which is the root of the suffering of patients with psychosis and mental illnesses.
Many of the strange behaviors of mentally ill patients are actually due to errors in their psychological programs, which are manifested to outsiders. Mental patients show such actions due to errors in the psychological program, which can somewhat relieve their suffering from the physiological pain caused by mental disorders. If the treatment forces the patient to stop these actions, not only would it not help with the condition, but it would increase their mental suffering.
Even psychotropic drugs are designed to directly control and influence the end result of psychological program operation, i.e., physiological response and physical action.
