Actually, these Māyāvādī philosophers, they are so great rascals they sometimes say like that, that Vyāsadeva is also mistaken. They have got the audacity to say Vyāsadeva . . . He is accepted as incarnation of Nārāyaṇa, who has given us the Vedic literature, so many books he has given: the Vedas, thePurāṇas, the Mahābhārata, Śrīmad-Bhāgavatam, Vedānta-sūtra. Everything is given by Vyāsadeva in writing, and he's accepted, Nārāyaṇa, incarnation of Nārāyaṇa, mahāmuni-kṛte. He is also Vyāsa-muni, but He is also mahāmuni-kṛte.
So there cannot be any mistake in the words of Vyāsadeva. This is the difficulty. If one does not come through the channel of disciplic succession, so they are in so many ways mistaken. Vyāsadeva is above all this. He is not an ordinary writer, for material description, for material name and faith. He cannot be mistaken. As Bhagavān, Kṛṣṇa cannot be mistaken, similarly Vyāsadeva, incarnation of Bhagavān, he also cannot be mistaken. Neither devotee of Kṛṣṇa can be mistaken. Devotee of Kṛṣṇa, he does not say anything as his own opinion. He never says. What Kṛṣṇa says, he says. He may be not perfect, but what Kṛṣṇa has said, that is perfect. Therefore a pure devotee, who does not say anything beyond which was spoken by Kṛṣṇa, therefore his statement is also without mistake.
Common man within this material world, he commits mistake: "To err is human." Even big, big personalities, they commit mistake. But nārāyaṇa paraḥ. He is transcendental. Kṛṣṇa is transcendental. There cannot be any mistake; there cannot be any illusion. Those who are within this material world, they have got four defects: they commit mistake, they are illusioned, and their senses are imperfect—bhrama, pramāda, vipralipsā—and they're cheaters. Because . . . just like modern-day scientists and philosophers, they propagate so many branches of knowledge, but when, on the crucial point, they are caught, they say: "I, I do not know perfectly. I do not know perfectly. We are trying to know. In future, we shall tell you the perfect." But if you are not in perfect knowledge, why should you take the post of a teacher? If your knowledge is imperfect, then whatever you speak, that is imperfect. Therefore with imperfect knowledge, why you should become a teacher? That is cheating. That is cheating.
Therefore purposefully Vyāsadeva is writing sri-bhagavān uvāca: where there is no cheating, no imperfection, no illusion, no mistake. Four things: no mistake, no illusion, no cheating and no imperfection. This is Bhagavān. Why we are taking Bhagavad-gītā so seriously? There are so many other books we can read, so many theories, so many philosophers, big, big philosophers. But we cannot take them, because they are defective. The author is sure to commit mistake. He is illusioned. Because his senses are not perfect, therefore imperfection. So with all these defects, we cannot accept anyone's knowledge.
