Prabhupāda: Anitya means temporary. You cannot stay here. That they do not understand. They're making research, making research. And if we ask them, "What you are doing?" "For the next generation—future." And what about your, your . . .? You're going to be a tree next life. What you'll do with your next generation? But he's ass. He does not know. He's going to stand before that skyscraper building, a tree, for ten thousand years, and he's making dum-dum-dum. Therefore he's an ass.
He does not know where he's going. And he's making provision for the next generation. What is the next generation? If there is no petrol, what you'll do, next generation? And how the next generation will help you? You are going to be a dog, cat or tree. So next generation, how he'll help you? Jīva ke karaye gādhā. Therefore he's an ass. He does not know his personal interest. And making research work. What research work? Simply śrama eva hi kevalam (SB 1.2.8). Simply laboring . . . what is called? Labor of love? Or what is that?
Prabhupāda: Therefore Bhāgavata says, bhave 'smin kliśyamānānām avidyā kāma-karmabhiḥ. Avidyā. Avidyā means ass, no intelligence. He does not know what is life, what is the course of life, how things are going on. He does not know. The more he is increasing his unnecessary desires, he's making himself entangled. That he does not know. He has to take freedom from the repetition of birth and death, but he's becoming more and more entangled. Avidyā kāma-karmabhiḥ.
This is Bhāgavata. In one line, the whole material existence explained. This is literature. In one line, there is thousands years' research work. In one line. Bhave 'smin. Now this bhave 'smin, you make research. Asmin, in this world, taking birth. So you have to learn so many things on these two words: How the living entities are taking birth in this world. Wherefrom he's coming, where he's going. What is his business. So many things in these two words, bhave 'smin. Kliśyamānānām. Struggle for existence. Why? Avidyā. Ignorance. What is that avidyā? Kāma-karmabhiḥ.
Prabhupāda: Activities of sense gratification. He's becoming entangled.
Svarūpa Dāmodara: So the modern scientific research means to increase the demands of the body, the bodily demands.
Prabhupāda: Yes, what they can do? Because they're rascal, foolish, just like children, they'll simply make their body dirty. That's all. He does not know anything. If you bring a small children, what they will do? They'll take this . . . you see. He does not know anything. He's a rascal. Similarly you scientists, you are all rascals. You do not know anything. Punaḥ punaś carvita-carvaṇānām (SB 7.5.30), chewing the chewed, making research. What research you can do? You do not know anything. What research you can do?
And Vedic injunction is, yasmin vijñāte sarvam evaṁ vijñātaṁ bhavati (Muṇḍaka Upaniṣad 1.3). If you know the Absolute Truth, then all other things become known. But you do not know what is Absolute Truth. Therefore you are in ignorance. If you know one thing, then you . . . just like you are talking. We are not official scientists or philosopher or anything. But why you are challenging, you are talking so boldly? Because we know one thing, Kṛṣṇa. Therefore we can say so boldly and challenge anyone. I'm not a D.A.C. like you. How I can challenge you? I'm challenging you. How? Because I know Kṛṣṇa. That's all.
