Svarūpa Dāmodara: In physical sciences, there's a branch called thermodynamics that deals with the transfer of heat and energy in different forms. So their three laws is called first law, second law and the third law. First law deals with the conservation of energy in different forms. And the second law, it is stated that the energy of the universe is constant. Just like in the Śrī Īśopaniṣad, the "Invocation, pūrṇa . . .
Prabhupāda: Yes. Pūrṇāt pūrṇam udacyate, pūrṇasya pūrṇam ādāya pūrṇam evāvaśiṣyate (Īśo Invocation).
Svarūpa Dāmodara: On the other hand, the second law says that the, the entropy, that means the randomness of the all natural, spontaneously occurring natural processes, always increase. The randomness . . .
Prabhupāda: But . . . thing is that they are studying the laws very nicely. That's good. But they should appreciate that who has made this law. That is their defect. They are studying how the laws of nature is working. That's nice. But they should appreciate at the same time: Who made such subtle laws that they are working so nicely?
That is our philosophy. We do not only study the laws and appreciate it, but we study the law-maker also. That is the difference between ourself and the so-called scientists. They are left, poor fund of knowledge. They cannot appreciate that there is a law-maker of these subtle laws. That is their defect. That is called poor fund of knowledge. And as soon as we accept law-maker, we have to accept that He's a person, He has got brain; therefore He can make laws.
Just like the great ocean is working, but there is a law. It cannot come here, although there is potency. At any second it can cover the whole city. But there is a law. Just like state law, "Up to this. No more admission. You have to stop." Similarly, there is law of God. Where there is order, "You mighty ocean, you cannot come beyond this," this is law. There is sun, "You must rise at half-past . . . at five o'clock in the morning." "Yes, sir." This is law, "You must rise on the eastern side." "Yes, sir." Not whimsically—sometimes this side, sometimes that side, sometimes that side. Cannot do whimsically. That is law of nature. And behind the law of nature, there is the order-giver, law-maker. This is perfect knowledge.
Mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram (BG 9.10): "Under My superintendence, the laws of nature is working." This is intelligence. We are teaching people this intelligence. That's all. We don't decry that, "Your studying of the laws of nature is useless." We don't say that. We say: "Not so much. This is imperfect. Go forward still." And that is perfection. You are a science student. By your scientific knowledge, you prove that behind these laws there is Kṛṣṇa. Then your scientific knowledge is perfect. Either from the chemical department or physical department or electrical department, any department, it doesn't matter—through that department you go to the ultimate center.
Just like here is center, and there are so many spokes. So many spokes. So whichever spoke you may be, come to the center. That is your perfection. The spokes may be of different direction, like that. But center is Kṛṣṇa. The energy, central energy, is Kṛṣṇa.
