- kibā vipra, kibā nyāsī, śūdra kene naya
- yei kṛṣṇa-tattva-vettā sei 'guru' haya
- (CC Madhya 8.128)
"Never mind whether he's a brāhmaṇa or a śūdra or a sannyāsī or a householder. Never mind what he is. That doesn't matter. If he knows the science of Kṛṣṇa, then he is the bona fide spiritual master." He is the bona fide spiritual master. So here this Bhagavad-gītā is the science of Kṛṣṇa. Every one of you, if you study Bhagavad-gītā very scrutinizingly, with all your arguments, with all your sense, with all your philosophical knowledge... Because it is said here, tad viddhi praṇipātena paripraśnena (BG 4.34). Not that you have to submit yourself blindly. Although your spiritual master may be self-realized and experienced in the Absolute Truth, still, you have to question. You have to understand from him all critical points by your intelligent questions. That is allowed. So it doesn't matter. If anyone is able to answer about the science of Kṛṣṇa, he is spiritual master. He is spiritual master. It doesn't matter where he's born or what he is, whether he's a brāhmaṇa, or a śūdra, or an American or an Indian or whatever he is. Never mind. Just like... It is practical. When you go to a doctor, medical practitioner, you do not ask, "Well, Doctor, are you American or Indian? Are you brāhmaṇa? Are you Jew? Are you Christian?" No. Oh, he has got the qualification of a medical man, so you surrender, "Doctor, treat me. I am suffering." So there is no question. So Caitanya Mahāprabhu has given liberal that "Anyone who knows the spiritual science, or the Kṛṣṇa science..." Kṛṣṇa science is spiritual science. Because Kṛṣṇa is the ultimate goal of spiritual science. When I speak of Kṛṣṇa, you must remember that I am speaking of God. There are millions of names of God in different parts of the world, but Kṛṣṇa is the supreme name according to Vedic knowledge. So therefore Lord Caitanya has recommended—and His recommendation is accepted by the authorities even at the present moment—
- kibā vipra, kibā nyāsī, śūdra kene naya
- yei kṛṣṇa-tattva-vettā sei 'guru' haya
- (CC Madhya 8.128)
And you'll be surprised that Lord Caitanya's principal disciples were all so-called fallen in the society. He appointed one Haridāsa Ṭhākura, Nāmācārya Haridāsa Ṭhākura. This Haridāsa Ṭhākura was a Muhammadan. He happened to take his birth in a Muhammadan family, but he became a follower of Caitanya, and Caitanya Mahāprabhu, after training him, He gave him the highest post of His spiritual mission. Caitanya Mahāprabhu appeared to introduce this system of Hare Kṛṣṇa Hare Kṛṣṇa Kṛṣṇa Kṛṣṇa Hare, chanting of the holy name of God, and He appointed this Haridāsa Ṭhākura, who happened to be a Muhammadan. But he became so much enlightened that Caitanya Mahāprabhu appointed him the supreme minister of administering this Hare Kṛṣṇa, Hare Kṛṣṇa. He was, he was made the authority, nāmācārya. Ācārya means the prime minister, the authority.
