If you want to eat meat, you can eat many other animals, there are. But don't eat the cows. This is Vedic civilization. Kṛṣi-go-rakṣya-vāṇijyaṁ vaiśya-karma svabhāva-jam. Paricaryātmakaṁ kāryaṁ śūdra-karma svabhāva-jam (BG 18.44). And those who are neither brahmiṇ—they have no brain to become brahmiṇ or to become kṣatriya or vaiśya—they are called śūdras. And śūdra's business is to serve the other upper three classes, laborer, worker classes, and satisfied with some service.
So here it is said that, tataḥ parīkṣid dvija-varya-śikṣayā: "He was educated and trained up by the best class of the brahmiṇs," not by the śūdras. Śūdra's training, what he can become? He can become a rascal, that's all. The training was entrusted to the first-class brahmiṇ, who is himself trained up to speak truth, satya śamo damaḥ, to remain clean, to become very simple in habit, to become master of knowledge, and practically application. Such person should be the trainer, should be the teacher. Not a third-class rascal becomes a teacher and professor. He has no idea how to speak truth. He is speaking all lies, theories, and getting Nobel Prize. Such a śūdra is honored at the present moment. You see? Who has no knowledge. So many so-called philosophers and scientist, simply speaking lies and untruth. They have no knowledge. As soon as you challenge them, they will say: "Yes, we are trying. In future we shall do it." But if you are trying, then where is your knowledge? Why you are taking the post of a teacher? You are a cheater. You have no full knowledge, and still, you are putting some theory to mislead the people.
For example, just like they are putting on this theory that matter, from matter, life has come, "All right, matter, life has come from matter. Just prove it.
