Prabhupāda: Eh? Mental speculation. When it is dry... So dryness also, sometimes it is, "Oh, it is very dry, bad." And again, say dry, we shall say, "Oh, today is very good." It is simply mental speculation.
Devotee: It is like wet stool and dry stool. It is still stool.
Prabhupāda: Eh? Yes. (Chuckles) Yes, that is the example. The dry part of the stool, they say, "Oh, this part is very nice." He forgets that, after all, it is stool. So what is the dry or moist? Just like they are making scientific advancement. But the death is there. So what is the use of your advancement or no advancement? One who has not advanced in science, he'll also die. And you'll also die, advanced. Then what is the good? You cannot protect yourself from death. Then what is the meaning of this "good"? "This is good. This is advancement, and this is not advancement."
Svarūpa Dāmodara: But the distinction, the good and bad...
Prabhupāda: That is your distinction. You have made such distinction.
Svarūpa Dāmodara: I think that depends on the consciousness of the individual.
Prabhupāda: Relativity, relativity, law of Relativity. What is, what is food for one is death for other, the same thing. So how you can say the food is good or bad? Is it not? "One man's food, another man's poison." So how you can distinguish this is food or poison? One man will say, "No, it is food." Another man will say, "It is poison." So how you'll distinguish? So this good and bad is simply mental speculation. Because it is in the material platform, there is nothing good. Everything is bad. Otherwise why Kṛṣṇa said, sarva-dharmān parityajya (BG 18.66). In the name of "dharma," so many rascaldom is going on. Therefore Kṛṣṇa says, sarva-dharmān parityajya. It is not dharma. And Bhāgavata says, dharmaḥ projjhita-kaitavo 'tra: (SB 1.1.2) "This cheating type of religious system is rejected from Śrīmad-Bhāgavatam." All so-called religions, they're simply cheating. Cheating. Dharmaḥ projjhita-kaitavaḥ. Kaitavaḥ means cheating. Everything is cheating. They say, "We are advancing." What you are advancing? The problem, birth-death, is there. So what is the meaning of your advancement? Dharmaḥ projjhita-kaitavo 'tra paramo nirmatsarāṇām (SB 1.1.2).
Prajāpati: This is the only means, then, to get off that manorathena.
Prabhupāda: Manorathena, yes. Manorathena means if you remain on that platform, then you have to reject again. Just they are doing, the so-called scientists, philosophers. They are putting forward some theory, and after some time they reject it. So if you remain on the mental platform, then this business of accepting and rejecting will go on. You'll never come to a conclusion. Therefore one has to rise to the spiritual platform. That is nityaḥ śāśvato 'yam, na hanyate hanyamāne śarīre (BG 2.20). That is eternal, everlasting.
