Doctors should first understand the cause of disease, then treat it with diet. Medicine should only be used if diet fails

First, modify the patient's diet and lifestyle and only then, if these do not effect a cure, treat with medicinals and acupuncture.

Whenever a great physician treats diseases, he has to be mentally calm and his disposition firm. He should not give way to wishes and desires, but has to develop first a marked attitude of compassion. He should commit himself firmly to the willingness to take the effort to save every living creature.
