So Kṛṣṇa comes. What is the mission of Kṛṣṇa? That we were talking in this morning. What is the mission of Kṛṣṇa? Paritrāṇāya sādhūnāṁ vināśāya ca duṣkṛtām (BG 4.8). This is the Kṛṣṇa's karma. Therefore Kṛṣṇa says, janma karma me divyam (BG 4.9). We come here, and Kṛṣṇa also comes here. So what is the difference? The difference is we are forced to come here by the laws of nature according to our karma. We do some activities, sinful or pious, mostly sinful. So we create another life, and we are forced to enter into such body. It may be now I am in the human form of body. Next life, according to my karma, I may be forced to enter into the dog's li..., dog's body. So we are forced. There is no, I mean to say, choice. I cannot say (to) nature that "Do not put me into the dog's body. Kindly put me into the king's body." No. Karmaṇā daiva-netreṇa (SB 3.31.1). This decision will be taken by superior authority. You cannot dictate that "I shall become like that." No, that is not possible. Karmaṇā daiva-netreṇa.
So we are forced to come here and suffer or enjoy the fruits of our last karma. That is one thing. But Kṛṣṇa is not like that. Kṛṣṇa does not come, being forced by nature or for His karma. Na māṁ karmāṇi limpanti na me karma-phale spṛhā (BG 4.14). Kṛṣṇa says that He also works, karma, to show example, but He is not affected by the result of the karma. Therefore Kṛṣṇa says, na māṁ karmāṇi limpanti na me karma... Neither He has got any desire to work for something to gain something. He is full. Why He should try for gaining...? We work something. We work to gain something, to make some profit. But Kṛṣṇa hasn't got to do any profit. He is self-sufficient. Whatever He wants, immediately present. Omnipotent, omniscient. Kṛṣṇa has nothing to do like that. Therefore why does He come? He has got a different mission. What is that? Paritrāṇāya sādhūnāṁ vināśāya ca duṣkṛtām. He says, "I come for this purpose, to rescue the sādhus, the devotees, and to cut down the demons." Paritrāṇāya sādhūnāṁ vināśāya ca duṣkṛtām (BG 4.8).
So vināśāya ca duṣkṛtām, this is not main business. For killing the demons, one cyclone wind is sufficient. If Kṛṣṇa orders Varuṇa that "You make a heavy cyclone in this quarter," hundreds and thousands of demons will be killed within a second. So this is not the purpose, for... He does not come for killing. But because killing business is another business, when He comes to protect the devotees, so He automatically, there are some demons: "Kill them also." Just like you go somewhere. Now, your not business to purchase something, but when you see, "Oh, it is nice. It is cheap price. All right, purchase it." So you did not go to a friend's place to make some business, but when you see, sometimes you do that. Similarly, it is not Kṛṣṇa's business. That, Kṛṣṇa has got many, many agents. Sṛṣṭi-sthiti-pralaya-sādhana-śaktir ekā chāyeva yasya bhuvanāni bibharti durgā (Bs. 5.44).
This durgā power is there. You have seen the picture of Durgā. She has got ten hands and different types of weapons. Now the Durgā-pūjā will be performed. You can see the Durgā deity. So ten hands, the material nature. Ten hands means ten directions: north, south, east, west, and then the four corners, eight, and up and down. So ten directions. So this material nature, Durgā, is controlling the whole universe, ten directions. Sṛṣṭi-sthiti-pralaya-sādhana-śaktir ekā (Bs. 5.44). Ekā. Chāyeva. But how she is working? Not independently. Sṛṣṭi-sthiti-pralaya-sādhana-śaktir ekā chāyeva. She is working just like shadow. The original body and the shadow body, they are two different. But the shadow body moves if the original moves. So therefore this word is used, chāyeva. This vast power, material nature... It is a very powerful... Sṛṣṭi-sthiti. It can create; it can destroy. At any moment, if there is some earthquake, the whole sea water may come and cover the land portion, and within the sea you can see one island has come out. Everyone has got this experience. So sṛṣṭi-sthiti-pralaya. One side, pralaya; one side, creation. So this can be done by the material nature. But how she is working? She is working under the direction of somebody else. That is Govinda. And Govinda also says in the Bhagavad-gītā, mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram: (BG 9.10) "She is working under My direction."
So... So far killing or destroying is concerned, that Durgā power, Kṛṣṇa's power, that is sufficient. That is sufficient. He doesn't require to come to kill the demons. She is engaged. You have seen that Durgā is killing the demon, that asura. You have seen the Durgā's picture? The asura is there and the lion is there, and she has taken a bunch of hair of the asura, and the trident is pushed on his chest, and the lion has captured him. So he is overpowered. So the asura is overpowered, but if the asura makes more attempt to save himself, then there are, only two hands are engaged of Durgā to kill the asura, one catching his hair and one the trident. Only two hands are engaged. But if he shows more power, then there are eight hands more, reserved with different types of weapons. So you cannot overcome the ruling, or the control, of the material nature. That is not possible. Daivī hy eṣā guṇamayī mama māyā duratyayā (BG 7.14). So asura, to kill the asuras, however powerful they may be... We have seen. There were so many asuras in this world. There were Lenin, there were Stalin, there were Hitler, there were Hiraṇyakaśipu. So many. But they could not survive. It is not possible. They'll be finished.
So asuras, to kill him... Paritrāṇāya sādhūn..., vināśāya... To kill the duṣkṛtām, these asuras, Kṛṣṇa does not require to come. He comes only to give protection and pleasure to the devotees. That is his aim. Therefore it is said that paramahaṁsānāṁ munīnām amalātmanām. For them, bhakti-yoga-vidhānārtham. For increase their bhakti-yoga. If you are a devotee of Kṛṣṇa, you are in distress by the demons, and if Kṛṣṇa saves you, then you become more: "More I am devotee, more I am devotee." You see. So Kṛṣṇa came so many times. Just like His devotee Prahlāda Mahārāja was in trouble by his father. So He came. Similarly, Vasudeva and Devakī was in trouble by Kaṁsa, therefore He came. So paritrāṇāya sādhūnām (BG 4.8). They are sādhus, they are devotees. For them He comes. Paritrāṇāya sādhūnām. So why He's interested to save him? Now, bhakti-yoga-vidhānārtham, to show to the people that bhakti-yoga is so strong, so nice, that it will protect you from all kinds of dangers. Kṛṣṇa says in the Bhagavad..., svalpam apy asya dharmasya trāyate mahato bhayāt. If you execute a little of bhakti-yoga, you can be saved from the greatest danger. Bhakti yoga is (so) nice. Buddhi-yogam imaṁ śṛṇu. These are discussed.
