The so-called scientists, thinker, they are thinking that "We are everything. We can create, and we can control over the nature." These are all mad thinking. It is not possible. Nobody has ever been able to control over the nature, what to speak of understanding God. God is the controller of nature. Mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram (BG 9.10). Nature is not independent.
So anyway, we are dependent on the laws of nature. That nobody can deny, even the greatest scientist, he cannot also deny. And because we are under the control of the laws of nature, we must admit, if we are sane man, that there is a system of ruling. If we deny the supreme ruler, we may do it madly, but there must be a systematic, I mean to say, action, reaction. So here is Dharmarāja. Just like we have got magistrate, so magistrate's duty is, when a criminal is brought before him, to judge what kind of punishment he should be allowed. Justice there is. Similarly, this Dharmarāja means the criminals are brought before him. Dharmarāja is appointed magistrate by the Supreme Lord. So everyone, after death, he is brought before Dharmarāja, the Yamarāja, and he judges what kind of next body this criminal will have. That is Dharmarāja. He is judged by his work. Karmaṇā daiva-netreṇa jantur deha-upapattaye (SB 3.31.1). Just like the magistrate punishes the criminal, what kind of punishment he should be awarded, how he will be allowed to live within the prison house. Just like a political prisoner. In our country just now they have. . . so many big, big leaders have been arrested. But they are not put in the same level of ordinary criminals. They are given all facilities. They are given nice house, servants and newspaper. They are given all facilities of indepen. . . outside life, according to the position. They are called first-class prisoners. And there are similarly second-class prisoners, third-class prisoners. So this is judged by a person.
So here we are all prisoners within the material world, and some of us are first-class prisoners, and some of us second class, and some are third class. Therefore, we see the higher class of men in the society, middle class of men in the society, either in human society or even animal society. There is first-class animal, second-class animal, third-class animal. In the trees also, the same work is going on by nature. Prakṛteḥ kriyamāṇāni guṇaiḥ karmāṇi sarvaśaḥ (BG 3.27). One tree is supplying mango, so this mango tree is respect; and another tree, which is producing nothing, they are cut and made into fuel, because useless, no use. So amongst the trees also you will find first class, second class, third class. Among the birds, beasts, animals, there is. . . Just like lion, he is also animal, and dog is also animal. They are not on the same level. Amongst the birds there are swans and there are crows. The crow is different from the swan, although they are birds. The standard of enjoyment by the crows is different from the standard of enjoyment of the swan, white swan.
