If everyone says I am lowborn, I am lowborn, so I also think I am lowborn. But I am not lowborn. Ahaṁ brahmāsmi. I am brahmāsmi. I am spirit soul. I am born of Kṛṣṇa. Kṛṣṇa is my father. Take like that. Think like that. That is twice-born. That is twice-born. So Kṛṣṇa says, māṁ hi pārtha vyapāśritya: "Anyone who takes shelter of Me, never mind what he is . . . never mind he is. He may be lowborn, he may be a śūdra, he may be woman, he may be whatever he may be." Te 'pi yānti parāṁ gatim: "He can also go to My kingdom."
So our duty is to become twice-born. Just by culture, by Kṛṣṇa consciousness, let us take another birth. Let us take another birth. Then you will be recognized brāhmin. Brahmā jānāti. As soon as you know Kṛṣṇa, you are brāhmin. Never mind whether you are born in America, Czechoslovakia or any other place. Doesn't matter. So try to become a brāhmin. Here is a chance.
But how to become a brāhmin? Simply by purchasing two-cent-worth this thread and getting on the body? No. There are qualities, karma. You have to act like a brāhmin, and you have to acquire the qualification of a brāhmin. Then you can become a brāhmin. There is no impediment. Never mind wherever you were born. That doesn't matter.
So here is . . . Bhagavad-gītā is giving a chance to everyone to become brāhmin or be qualified person who knows Brahman and who is preparing himself for the next birth in the spiritual kingdom. He is called brāhmin. Cātur-varṇyaṁ mayā sṛṣṭam (BG 4.13).
