(Srila Prabhupada's books)
"So the whole world is in darkness. Therefore there is struggle. One is capitalist, one is communist, one is this, one is that, and there is struggle because everyone is in ignorance, māyā andhakāra, in darkness of ignorance. And Kṛṣṇa is light. Ignorance fighting will not make any solution of the problem. We must come to the light and take knowledge from the most enlightened, Kṛṣṇa, Bhagavān.
Bhagavān means He is endowed with six kind of opulence. He is the supreme rich. He is the supreme famous. He is supreme beauty and supreme wise. We have to take knowledge from the supreme wise. That knowledge is perfect. Therefore here it is said, bhagavān uvāca. He did not say kṛṣṇa uv... Vyāsadeva does not say Kṛṣṇa because Kṛṣṇa may be taken by the demons as something like us. So therefore he purposefully says, bhagavān uvāca. Bhagavān uvāca means the Supreme Personality of God. There cannot be any doubt about His knowledge. So bhagavān uvāca, whatever Bhagavān says, that is fact; that is not knowledge like that 'It may be,' 'Perhaps.' These are all rascaldom. 'It may be, perhaps'—that is not knowledge. That is speculation. Speculation is different.
And knowledge is different. You cannot speculate about the absolute knowledge because our senses are imperfect. How we can speculate or come to the right conclusion? That is not possible. We must receive direct knowledge. This is this. Therefore it is said, bhagavān uvāca. So whatever Bhagavān will speak, that is absolute knowledge. And if we take it, then we shall be perfect. I may be imperfect, you may be imperfect, but when we take knowledge from the perfect, that knowledge is absolute.
Just like a child does not know something, what it is, but if he asks his father, 'Father, what it is?' and the father will not cheat, he will give him the right knowledge, 'This is this,' so he may be a small child, imperfect, but because he receives the knowledge from his father, who knows, that knowledge is perfect.
Similarly, we receive knowledge from Bhagavān, and we distribute that. We don't make any addition or alteration. Therefore we present Bhagavad-gītā as it is. We don't make any addition or alteration. Therefore it is perfect. The Kṛṣṇa consciousness movement, whatever knowledge they are spreading, that is perfect. Don't think the man who is spreading, he is imperfect. He may be imperfect. He is imperfect. I am imperfect. Every one of us is imperfect. But we are not spreading the imperfect knowledge because we are simply spreading what Kṛṣṇa has said. We are repeating. That's all.
So this is our Kṛṣṇa consciousness movement, to distribute perfect knowledge, Kṛṣṇa consciousness, and that will make the whole world happy. So try to distribute this knowledge to your best capacity. Kṛṣṇa will recognize you, that you are trying your best to work on His behalf because He comes down to distribute the knowledge. Yadā yadā hi dharmasya glānir bhavati bhārata, tadātmānaṁ sṛjāmy aham (BG 4.7). Because we are all His sons—we are suffering—so He wants to see that our sufferings are mitigated immediately. But we are obstinate. We don't accept the supreme father's advice. That is our difficulty. He says repeatedly,
mām ekaṁ śaraṇaṁ vraja
ahaṁ tvāṁ sarva-pāpebhyo
mokṣayiṣyāmi mā śucaḥ
But we will not accept it. This is our misfortune. So voluntarily we should try to accept the knowledge and instruction given by Kṛṣṇa. Then our life will be perfect."
