There is no difference between laws of nature and laws of God. Laws of nature means laws of God. Dharmaṁ tu sākṣād bhagavat-praṇītam (SB 6.3.19). Therefore Bhāgavata says that religious principle cannot be manufactured by any human being. It is the law of God. Therefore one has to obey. One cannot disobey. Law of nature you cannot disobey. It will be enforced upon you. Just like law of nature, the winter season. You cannot change it. It will be enforced upon you. Law of nature, summer season, you cannot change it anything. Laws of nature or laws of God, the sun is rising from the eastern side and setting on the western side. You cannot change it, anything.
That you have to understand, how laws of nature is going on. That is Kṛṣṇa consciousness, to understand laws of nature. And as soon as speak of laws of nature, we must accept that there is a lawmaker. Laws of nature cannot develop automatically. There must be some authority on the background. Bhagavad-gītā therefore says in the Tenth Chapter that mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram: (BG 9.10) "Under My direction, superintendence, the material laws are working."
