Don't think that because you are born in America, you cannot become a brāhmaṇa. No, you can become a brāhmaṇa. There is no restriction. Brahma jānātīti brāhmaṇaḥ. The formula is that janmanā jāyate śūdraḥ saṁskārād bhaved dvijaḥ. Janmanā jāyate śūdraḥ. Everyone who is born, first born by the father and mother... Then he is called a śūdra. Even he is born in a brāhmaṇa family, he is called a śūdra. Then saṁskārād bhaved dvijaḥ. Then, by culture... The cultural birth is called the second birth, dvija. The higher caste in India, they are called dvija. Dvija means the first birth by father and mother, that is... Animal birth and man birth is the same because the process is the same. But unless one takes his birth by higher culture, he cannot be called dvija.
Sometimes the birds are also called dvija. Dvija means twice-born. Twice-born. Just like the birds... The sea bird lays the egg first, and then it is fomented. And from the, I mean to, the egg, the cub comes out, the offspring comes out—the second birth. Therefore birds are also sometimes called dvija. Similarly human and higher status of life, they must have twice-born. Therefore the brāhmaṇas, the kṣatriyas, and the vaiśyas, this thread, this thread is the sign that "My second birth has been done." This is the emblem. This upavīta, upanayanam, this is the sign. In India higher caste you will find this sacred thread. Sacred thread means when he is accepted, when he is given the second birth, this thread ceremony, there is a thread ceremony. So second birth means saṁskāra, saṁskāra, reformation, reformation. It doesn't matter where and how he is born. It doesn't matter.
