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.
So this kind of artificial going up and making things negation will not help us. That is not possible. Therefore they are failure. Āruhya kṛcchreṇa paraṁ padaṁ tataḥ (SB 10.2.32). These Māyāvādī philosophers, they may go very high by knowledge, by speculation, but they will again fall down. Why? Anādṛta-yuṣmad-aṅghrayaḥ: "Because they could not get the shelter of Your lotus feet, therefore they will fall down." That is not secure. Because a man cannot remain without any activity, without any desire. That is not possible. A man, animal, any, even insect, he must be doing something. I have got practical experience. One of my sons in child..., when I was young man, he was very naughty. So sometimes we used to put him on the rack. He could not get down. So he was feeling so uncomfortable because his activities stopped on the rack. So you cannot stop activity. That is not possible. You must give better activity. Then you will stop. Paraṁ dṛṣṭvā nivartate (BG 9.59).
So this Kṛṣṇa consciousness movement is that you get better activity. Therefore you can give up the inferior activities. Otherwise, simply by negation, it is not possible. We must work. We must work for Kṛṣṇa's sake. We shall go to the Kṛṣṇa's temple, or we shall go for selling Kṛṣṇa's books, or meeting some Kṛṣṇa devotee. That is nice. But you cannot stop working. That is not possible. Then your idle brain will be devil's workshop. Yes. Then you will fall down, "How to go to that woman? How to go to that man?" If you stop working, then you have to work again to sense gratification. That's all. Similarly, you take any sense; you cannot stop it, but you have to engage it. That is Kṛṣṇa consciousness. You engage your hand and engage your legs, you engage your eyes, you engage your ears, engage your tongue—simply in Kṛṣṇa. You can engage everything. For eyes, instead of hankering after some beautiful man or beautiful woman, just see Kṛṣṇa, how nicely dressed. Then you will forget these other seeing. For tongue, you engage your tongue simply for chanting. Then your nonsense talking will automatically stop. You engage your tongue eating very nice prasādam of Kṛṣṇa, offered to Kṛṣṇa. Then you forget to go to restaurant. In this way our time should be utilized. As it is said that kim anyair asad-ālāpaiḥ. We should not allow our senses to be engaged in such thing which will never exist. That is the criterion. Simply engage yourself in such things which will continue, will exist forever.
