Not simply acquiring the quality, but he must work as a Brāhmin. Then he will be accepted as a Brāhmin. Now everything is thrown away. If somebody happens to take birth in a Brāhmin family, he becomes a Brāhmin. All others, Śūdra. And he may do all nonsense, and still he is Brāhmin. That is not . . . it is the duty of the state to see whether you are qualified as a Brāhmin. "You are claiming as Brāhmin. Whether you are actually qualified as a Brāhmin? Whether you are working as a Brāhmin?" It is the state's duty to see. It is the king's duty. He may not misguide others.
Just like nowadays a so-called Brāhmin is working as a cobbler, and he is claiming to become Brāhmin. Not like that. It is the . . . just like a medical man. A medical man, if he wants to practice, then he must get certificate from the medical board, registration. The medical board will see whether he is qualified as a medical man, whether he has passed medical examination. Then he will be allowed to practice as a medical man. So whenever a medical practitioner gives you a prescription, along with his name, he gives his title, M.D., B.S., and registered number. That means he is approved. Then he can practice. This is commonsense affairs in the every state. A lawyer is given certificate by the government, then he is allowed.
Similarly, it is the duty of the state or of the monarch to see that one who is claiming as a Brāhmin, whether he is qualified, whether he is acting as a Brāhmin. Similarly, a man claiming Kṣatriya, whether he is qualified as a Kṣatriya and he is acting as a Kṣatriya. Similarly, the Vaiśya. And Śūdra is general. Śūdra means one who has no education, no culture. That is called Śūdra. So that is the remnants. First of all, Brāhmin, Kṣatriya, Vaiśyas; and others, those who have no sufficient brain, they are counted as Śūdra. Still, Śūdras have also prescribed duties.
