The job of giving treatment cannot be performed by anybody, because that work and its result is directly connected with the life of sick persons. So if an ordinary man starts doing the work of giving treatment, sometimes the life of a patient is put in danger. For this reason, there should be a fixed qualification for giving treatment by a physician. In addition to this qualification, there are some other matters also which a physician must have. For e.g. a physician should have memory power, he should have knowledge about remedy and the purpose. Also, he should be a conqueror of soul i.e. he must have conquered his soul and finally carry out proper examination, diagnose and then give treatment. He should be like this. Such a physician can give treatment to a sick man.
