So this Kṛṣṇa consciousness movement is that medicine by which you can conquer over death. Therefore this is the best medicine. Bhavauṣadhi. It is said in the Śrīmad-Bhāgavatam, bhavauṣadhi. Nivṛtta-tarṣair upagīyamānāt... (aside:) You can stand on the wall, not in the middle. Nivṛtta-tarṣair upagīyamānād bhavauṣadhāt (SB 10.1.4). This word bhavauṣadhi means the panacea for all material diseases. Bhavauṣadhāc chrotra-mano-'bhirāmāt. Parīkṣit Mahārāja says that this chanting of Hare Kṛṣṇa mantra, it is chanted by whom? Nivṛtta-tarṣaiḥ, one who has finished his hankering after material pleasure. Nivṛtti. Nivṛtti means finished, no more. There are two ways: pravṛtti and nivṛtti. I want to smoke—that is called pravṛtti. And when I give up, that is called nivṛtti. Pravṛtti and nivṛtti.
So there are two things: pravṛtti and nivṛtti. But asuras, demons, they do not know "In which way I shall guide my pravṛtti and which way I shall guide my nivṛtti." This is the paśu. "In which way I will..." Pravṛtti and nivṛtti, these two things are there, but the difference between a demon and demigod is that a demon does not know how to direct these two propensities, pravṛtti and nivṛtti. And a demigod knows how to guide these two things, pravṛtti and nivṛtti. These two...One who does not know... Pravṛttir eṣā bhūtānāṁ nivṛttis tu mahā-phalā. Śāstra says that these things... Just like, loke vyavāyāmiṣa-madya-sevā nityā hi jantor na hi tatra codanā. This eating, sleeping, mating and defending, every animal, every small animal, knows it very well, how to eat, how to sleep, how to have sex intercourse and how to defend. These four things, everyone knows by nature. So this is called pravṛtti. Pravṛtti. But it has to be made nivṛtti, stop. They do not know what is the perfection. The perfection is... The pravṛtti, propensity is eating, sleeping, mating, defending. And when you make it just the opposite—no more eating, no more sleeping, no more mating, no more defending—oh, that is perfection of life. Who knows this? Ask any scientist, philosopher, of this world, that "Can you show me any way, no more eating, no more sleeping, no more mating and no more defending?" That is spiritual life. Therefore we have to reduce it. It is not possible, but there is possibility. Just like Raghunātha dāsa Gosvāmī. Raghunātha dāsa Gosvāmī, he made it in his life, during Caitanya Mahāprabhu's... Even after departure of Caitanya Mahāprabhu, about four hundred years ago. He was a very rich man's son. Very good wife, very good state. He left everything, and ultimately, he made these things, even eating, nil. He was eating every third day a small quantity of butter, nominal, little. Otherwise he gave up eating. So it is possible. It is not that "How one can give up eating and live at the same time?" That is possible. By the life of Raghunātha dāsa Gosvāmī we see.
So actual civilization means to deny material conveniences. That is actual civilization. That is perfection of civilization. Otherwise the cats and dogs, they are also after food, after sleeping, after sexual intercourse, after defense. Then what is the difference? The difference is the animals after it and the human beings should be not after it. Negation. That is perfection of life. So how we can negate? The Māyāvādī philosophers, they want to negate. Or the Buddhist philosopher. "Make it zero. Make it zero." Śūnyavādi. Śūnyavādi. Nirviśeṣavādi. Nirviśeṣavādi and śūnyavādi, almost the same. So they are after negation. But that is not possible. Artificially, if you negate, "I shall not eat," you cannot continue it for very many days. That is not possible. That is not possible. Similarly, eating, sleeping, mating—everything—artificially you cannot do. But you can do it as perfectly, as much possible, simply by Kṛṣṇa consciousness. Therefore it is said here that kim anyair asad-ālāpaiḥ. If we stop hear Kṛṣṇa talking, then that is negation. If we stop artificially these mundane talks, that will be artificial. You cannot sit down. If I say that the so-called meditation... So meditation is artificially stopping mundane activities. That is meditation. But how long you will do that? He is becoming suffocated, "When I shall talk? When I shall talk? I am meditating, meditating, meditating." But how will it stop? That is not possible. Just like these Māyāvādī philosophers, they say, "Become desireless, no more desire." That is not possible. I am a living entity. How can I be desireless? It is not possible.
So this negative process will not help us, śūnyavādi. Śūnyavādi. Nirviśeṣavādi. It will not be helpful. Therefore in the śāstra it is said that āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanty adhaḥ anādṛta-yuṣmad-aṅghrayaḥ (SB 10.2.32). The same example I have given several times, that these rascals, they are going to the moon planet and sun planet, but they do not get any shelter, and they come down again. Their advancement means go to some extent and again come back again, earthly planet. When the Russian aeronauts was flying, he was seeing, "Where is my Moscow? Where is my Moscow?" The anchor is there. The attraction is there in the national, in the country, in the city, in the home, in the wife, in the cats, in the dogs. And he is trying to go up. So that is not possible. Just like a vulture. He goes three miles up or more than that, but his aim of life is to find out a dead body. That's all. He is finding. He has gone so up. You can see that advancement of going up, but the business is to see where is a dead body so that he can eat.
