A Matter Of Qualification - Prabhupada 0612

We have already discussed this matter, that brahmin does not mean a particular class or born in a particular country. A brahmin means who knows the position of the soul, or the constitution of the soul. He is brahmin.
Just like a person who is conversant with medical science, he is called medical man or a doctor. It doesn't matter whether he is born in India or born in America or whether he is black or white. It doesn't matter. One must have the qualification of a medical man, and he is called a doctor.
