Puṣṭa Kṛṣṇa: So this verse, mūḍho 'ya nābhijānāti, that the mūḍhas, they can't perceive Kṛṣṇa. So actually it's simply that we're covered, isn't it? But Kṛṣṇa is always there.
Prabhupāda: Kṛṣṇa is always there, but yogamāyā-samāvṛtaḥ. He does not know Kṛṣṇa on account of being covered by the curtain of yogamāyā. Nāhaṁ prakāśaḥ sarvasya yogamāyā-samāvṛtaḥ (BG 7.25). But we can make them all happy by Kṛṣṇa consciousness, if they follow our instruction, even in this material world. Pūrṇaṁ sukhāyate. Full happiness we can give them if they follow our principle.
Cyavana: They have so many doubts.
Prabhupāda: What is the doubt? Doubt means they cannot drink, they cannot continue slaughterhouse, they cannot continue brothels. That's all. This is their doubt, that "How these things will be maintained? This is our life." That is doubt, and that is the difficulty. As soon as we say, "No this," oh, they are in danger. Even Marquis of Zetland, "Oh, it is impossible to give up. This is our life." There is the difficulty. Otherwise, there is no difficulty. They cannot think of, especially the Westerners, that without these things one can live. So many, our disciples, left. Rāyarāma left: "Oh, Swamiji is denying the preliminary necessities of life." This is the preliminary necessities of life: illicit sex, meat-eating, drinking, gambling. They cannot think that a man can live without these things. Therefore people are wonderful, that "How he is turning these Europeans, Americans to this standard?" That is their wonder. Nobody can think of, that these things can be given up and one can avoid it. It is dream. Your government, American government, is also surprised that "We have spent so much money for stopping this LSD, and this man by saying his disciples, they are giving up." Judah has also mentioned that. That is their surprise—"How these things can be given up? It is impossible."
Puṣṭa Kṛṣṇa: You once said in Geneva that no one has died by giving up smoking.
Prabhupāda: Yes. Actually that is the fact. You have given up these four bad things, and what is your wrong, harm? Rather, you have become bright-faced. But they will not give it up. They think, "It is impossible."
