In the Vedic literature all these informations are there. And as Kṛṣṇa says, personally, also . . . Arjuna accepted that, "I accept, on the authority of Vyāsadeva, Nārada, Devala, Asita, You are the Supreme Personality of Godhead, and You also speaking directly. Then where is my doubt?"
So we should follow . . . this is called paramparā system. As Arjuna understood Bhagavad-gītā, if we understand that way, then we are perfect. I may be imperfect, but because I understand Bhagavad-gītā as it was understood by Arjuna, I am perfect. Because the knowledge I am distributing, that is not imperfect. Just like a post peon. A post peon is delivering you one thousand dollars.
So he may be poor man, but the one thousand dollar he is delivering, that is a fact; that is not bogus. Because he has not manufactured something. He has received that money order from the post office. He's asked to deliver it to such-and-such person. His honesty is to deliver the money order as it is to the bona fide person. That is his perfection. He doesn't require . . . because he's delivering one thousand dollar, he doesn't require to become a very rich man. He may be a poor man.
Similarly, a guru, a guru is perfect when he delivers the words of the superior authority as it is. Then he's perfect. He may be imperfect in your estimation. But that is his perfection, that he is not misleading people by becoming a so-called rascal scholar and interpreting in a different way and misleading the whole population. That is perfection. People say so much about me, that I have done some wonderful thing. But I say that I am not a magician. I'm not a magician. My only credit is that I am presenting Kṛṣṇa as He is. That's all. I am not diluting Kṛṣṇa. That is not my business.
And therefore, because it is pure, pure ghee, therefore everyone accepts. And if you place dalda, mixing with ghee some rascal thing, then nobody will accept. Therefore, so many svāmīs went before me in the Western countries, and they presented adulterated, and there was not a single person became a kṛṣṇa-bhakta. Now, by thousands they are becoming. Why? Because it is presented pure thing.
Pure thing will be accepted everywhere. I give this example. In a, in Delhi, there is . . . I have seen, one, there is confectioner's shop. He rigidly prepares in pure ghee all the sweetmeats. So you'll find always hundreds of customers there. And there are by the side of that, there is dalda manufacture. It is not . . . people are still prepared to pay sufficiently if you give pure thing.
So our this Kṛṣṇa consciousness movement is presenting Bhagavad-gītā as it. We have not manufactured anything. While I started this movement in America, some friend suggested that, "You are writing 'International Society for Krishna Consciousness'? Why not make it 'God consciousness.' It will be accepted by everyone." No. God is Kṛṣṇa. There must . . . there must be clearly stated: "Krishna consciousness." I don't mind if nobody accepts it, but there must be 'Kṛṣṇa.'
