So nobody is uncontrolled. Now, so many big, big planets, huge planets . . . this earth planet is only . . . it's a minute, small planet, and still, you'll see, on this planet there are so big oceans like Atlantic and Pacific, and so big mountains, and what to speak of your skyscraper buildings. With all this load it is floating in the air just like a swab of cotton. Who is controlling? Can you float even a small piece of grain in the space? You can say "law of gravity" and so many other things, but you cannot utilize it. Or you can put it in . . . your machine, airplane, is running on the space—but so long the machine is working. As soon as your petrol is finished, immediately it will fall down. Immediately.
But these big, big planets . . . this is only one of the small. The sun planet is fourteen hundred thousand times bigger than this planet. So that is also . . . we can see the sun is floating in one corner of this big space. So how you can say that it is not controlled; it is floating out of its own self? No. The answer is there in the Bhagavad-gītā, that "I enter into this material planets, and then I keep it floating." Gām āviśya aham, dhārayāmy aham ojasā (BG 15.13). Dhārayāmy aham ojasā. Something mak . . . just like you float this airplane; so somebody has entered within it, that driver or pilot. So actually, he is keeping this airplane floating, not the machine. This is simple truth.
So if you take this analogy, then this planet is floating, there must be somebody entering here. Somebody must have entered. So Kṛṣṇa says, "I have entered." So what is the difficulty to understand how it is keeping floating? The analogy is there. Everyone can understand that this big airplane is floating in the sky because the pilot has entered within it. Similarly, if this planet is floating, then somebody, either you or somebody, God, has entered it. And that answer is there in the Bhagavad-gītā, that "I enter into these planets, and therefore I keep them floating." That is our answer. And the scientists, they say the law of gravitation . . . how far it is true . . .
But we have to take knowledge from Kṛṣṇa. Our process is that. We don't accept any other process of knowledge. Our knowledge is to receive the knowledge from the authority, and that is fact. That is first-class knowledge. If you get one authority who can speak on the subject matter, and if you take that knowledge, that is perfect.
There are three kinds of processes to receive knowledge. The first: we believe direct sense perception, pratyakṣa. Just like somebody says, "Can you show me God?" That means they are pratyakṣavādi. They want to see everything direct, experience everything directly. This class of men says that "Can you show me God?" But this is not first-class knowledge. Suppose you ask me, "Can you show me God?" I say, "Yes, I can show you God." "Show me." "I'll show you. So this is God." Will you believe it? Suppose you are asking me, "Can you show me God?" I say, "Yes, I can show you." "What is that God?" "Here is God," I say. So will you accept it that this microphone is God? What is the answer? Huh? Why no?
