Objectives: To research the needed Buddhistic ethical beliefs and psychotherapy from representative medical records of oriental medicine. Methods : The baseline data this research used is Myeong-Ui-Lyu-An, Sok-Myeong-Ui-Lyu-An, Ui-Bu-Jeol-Lok and from the variety of medical records; we extracted 22 medical records that refer to Buddhist thoughts. The sequence of medical records is determined by analyzing the contents of all medical records and grouping them by their categories. Results: The representative ethical mind that a doctor needs is the `mercy thought` from Buddhism. This way, the doctor has ``pity`` on patients and expects no reward for what he had done. `Spells and religious beliefs developed into medical treatment procedures by Buddhism and oriental medicine psychotherapy. Using the belief that everything is made of the mind, which is the point of the `Hwa-Eum` theory and the realization that the psychotic factors have a big role in the occurrence and progress of sicknesses, we emphasized supportive psychotherapy or more specifically, the suggestive therapy. ``Anguish`` is an important point in the occurrence and progress of illnesses. To solve this, we used ``Zen family`s ``Zen self-discipline`` and ascetic life from Buddhism. According to Buddhism, a human`s metal conflict and love or malingering from obsession is the cause of all mind illnesses. To heal these, a doctor must have an insight of the patient`s mind more than the symptoms. Conclusions: Buddhistic thoughts suggested clearly the mentality necessary for oriental medical psychotherapist and medical ethics for a doctor.
