Bhūrijana: They say that change is the principle. They say that change is the highest principle, and out of so many different changes . . .
Prabhupāda: No. How the change takes place?
Bhūrijana: Change. Change. C-h-a-n-g-e.
Prabhupāda: Change, I say. How the changes take place? You are changing. You are changing from your childhood to boyhood, boyhood to youthhood. So there is a plan. Unless there is plan, why one child is not, by chance, becomes immediately old? What the nonsense will reply? Let the rascal reply this, that here is a chance, that one child immediately becomes old man, by chance. Why there is process? This is plan. So you should have depth of knowledg, otherwise you will be carried away by these rascals. We cannot be carried away by these rascals. We never so easily believed that they are going to the moon planet. You see?
We have to scrutinize everything. Yes. That is Brahminical qualification. A Brāhmin will not accept anything simply because it is said by some rascal. A Śūdra will accept, because he has no intelligence. That is the difference between Brāhmin and Śūdra. It is not a caste system. It is classi . . . guṇa karma vibhāgaśaḥ (BG 4.13), division of high qualities and actual activities according to that quality. They misinterpreted. Because by the influence of Kali-yuga everyone is Śūdra, so he does not know what is the actually Brahminical qualification. Therefore there is, I mean to say, competition: "Why this man should be done? I am as good as he is, and why he should be called Brāhmin, he should be given greater facility?"
So actually it has happened so. A so-called Brāhmin, caste Brāhmin, he is working his intelligence like Śūdra, and he is claiming, by birthright, Brāhmin. There must be protest. This has happened. Otherwise, that division is perfect, guṇa karma vibhāgaśaḥ. Anyone who comes to that quality, he becomes Brāhmin. That is the injunction of the śāstra. Kṛṣṇa says, guṇa karma vibhāgaśaḥ. You have no qualification, you do not work according to your quality, and why you are claiming a Brāhmin? That is self-evident. Guṇa karma vibhāga. He never said: "By birth." Never said. Kalau śūdra-sambhavaḥ. "In this age, Kali-yuga, all Śūdras." Therefore they accept everything cheaply and at once, the Śūdras.
