Veda pathād bhaved vipra, and when he is allowed to study this Vedic literature . . . without becoming dvija, one cannot understand this Vedic literature. Just like without becoming a graduate, you are not allowed to enter in the law court. Similarly, without becoming a dvija, you are not allowed to study the Vedas, because you will not understand. Saṁskārād bhaved dvijaḥ veda-pathād bhaved vipro. And when by studying the Vedic literature he understands Kṛṣṇa, then he becomes a Brāhmin. Vedaiś ca sarvair aham eva vedyam (BG 15.15).
Because the purpose of studying Vedas means to understand Kṛṣṇa, or God. When I speak of Kṛṣṇa, you understand God. So when one understands what is God, what is Brahma, what is Kṛṣṇa, what is Paramātmā, then he is a Brāhmin. This is the process. So the Garga Upaniṣad says that anyone who dies after becoming a Brāhmin, his life is successful. And anyone who dies without becoming a Brāhmin, he dies like a cat and dog. That is the difference.
So our this Kṛṣṇa consciousness movement is that don't die like cats and dog, die like a Brāhmin. That is our request. Don't think it is any sectarian religion. It is a science. It is a culture. You are trying to educate people how to become Brāhmin. Just like these European, American boys, they are not born of a Brāhmin family. According to Vedic understanding, they are born in the family of mleccha or yavanas or caṇḍālas, like that. There are different terms. But Bhāgavata says never mind what he is, or Bhagavad-gītā says never mind what he is.
In the Bhagavad-gītā you will find the statement by Kṛṣṇa: māṁ hi pārtha vyapāśritya ye 'pi syuḥ pāpa-yonayaḥ (BG 9.32), "Anyone, it doesn't matter what he is, even he's born in sinful family, it doesn't matter. If he takes shelter of Me:" māṁ hi pārtha vyapāśritya te 'pi yānti parāṁ gatiḥ, "they all are promoted to the supreme planet, back to home, back to Godhead." Kiṁ punar brāhmaṇāḥ puṇyā (BG 9.33), then if they can be promoted, what to speak of persons who are really born in the Brāhmin family.
