One who has actually seen or actually realized the truth, you have to take knowledge from there. So we have to approach such person. Otherwise, if we approach some speculator, we cannot get real knowledge. So those who are speculators, they cannot understand what is God. Therefore they commit mistake that, "God is like this," "God like that," "There is no God," "There is no form." All these nonsense things are proposed, because they are imperfect. Bhagavān therefore said, avajānanti māṁ mūḍhā mānuṣīṁ tanum āśritāḥ (BG 9.11). Because He comes for our benefit in the human form, the fools and rascals consider Him as ordinary person. If Bhagavān says, ahaṁ bīja-pradaḥ pitā (BG 14.4), "I am the seed-giving father," so, every one of us, we know that my father is person, his father is person, his father is person, and why the Supreme Person or the supreme father should become imperson? Why? And therefore we have to learn from Bhagavān, the Supreme Person, full knowledge. This Bhagavad-gītā is therefore full knowledge from the full Personality of Godhead. We cannot change even one word in this Bhagavad-gītā. That is folly.
So our this Kṛṣṇa consciousness movement is following this principle. We don't manufacture any concocted things. We simply distribute the message given by the Supreme Personality of Godhead. And this is becoming effective practically. You can see practically these Europeans and Americans, Australians, all over the world, they did not know four or five years ago, or say ten years ago, since I have begun this movement, they did not know what is Kṛṣṇa. Although Bhagavad-gītā was being presented by so many svāmīs and yogīs, not a single man became a devotee of Kṛṣṇa. So our this presentation, because it is pure, without any adulteration, it is acting very nicely. Even the Christian priests, they become surprised when they see that these boys, their boys—they were Christian or Jews—they become surprised that "These boys, who were never coming to the church, they were never interested in understanding what is God, now, since this Kṛṣṇa consciousness movement is there, how these boys have become so mad after God?" The only reason is that we are presenting Bhagavad-gītā as it is. We preach that Kṛṣṇa is the Supreme Personality of Godhead. Kṛṣṇa says also in the Bhagavad-gītā, mattaḥ parataraṁ nānyat kiñcid asti dhanañjaya (BG 7.7). So this is being effective, that if we really want to understand Bhagavad-gītā, we must understand as it is presented by the Supreme Personality of Godhead. This is the instruction of Śrī Caitanya Mahāprabhu. Our this Kṛṣṇa consciousness movement is the movement which was given to us by Lord Śrī Caitanya Mahāprabhu. Śrī Caitanya Mahāprabhu's instruction is this. He says, āmāra ājñāya guru hañā tāra ei deśa (CC Madhya 7.128).
