Prabhupāda: Therefore why a śūdra artificially should be a brāhmaṇa? Let them, let him remain a śūdra, and if he follows strictly the rules and regulation of śūdra, he'll also be as good as a brāhmaṇa. The same example: Just like head is as important as my leg. It is not that because it is leg, it is less important than my head. And if you ask the head, "Do the work of a leg," it is impossible. And if you ask the leg to work as a brain, that is impossible. Let him remain brain, let him remain leg, and do your duty and you become perfect.
Satsvarūpa: Today you've been saying that the Vaiṣṇava is the highest, above the brāhmaṇa. But then we've also understood that everyone in ISKCON is a Vaiṣṇava.
Prabhupāda: Yes. Vaiṣṇava everyone, even if he's not brāhmaṇa. Jīvera svarūpa haya nitya-kṛṣṇa-dāsa (Cc. Madhya 20.108-109). But you have to gradually bring him to that pure consciousness that "I am servant of Kṛṣṇa." Here the bodily conception is going on, "I am American," "I am Indian," "I am this," "I am that."
Satsvarūpa: If in our society we say, "Śrīla Prabhupāda wants some to be śūdra..."
Prabhupāda: No, no, no. I don't want. I want everyone to become Vaiṣṇava. But because he's a śūdra, it is not possible to bring him immediately to the platform of brāhmaṇa, or Vaiṣṇava. Therefore falling down. Therefore system must be. But even if he remains a śūdra, he's a Vaiṣṇava.
Hari-śauri: So we'd have to completely revise the whole system that we have now.
Prabhupāda: No. Whatever we have, that is all right. But we see by experience that they're falling down. There must be systematic. Why falling down? Because he was not fit for the position, therefore he has fallen. Better remain in his position and become perfect. Why artificially bring them? There is no need. Kṛṣṇa says. Bring that Bhagavad-gītā. Sve sve karmaṇy abhirataḥ?
