So Kṛṣṇa's purpose of appearing is mentioned here. Paritrāṇāya sādhūnāṁ vināśāya ca duṣkṛtām (BG 4.8). Vināśāya means for annihilating, for killing. So Kṛṣṇa's killing is also good for the person who is killed by Kṛṣṇa. And another killing is to dissipate his ignorance. This is also . . . one is in ignorance, he does not know what is the value of life. Therefore Kṛṣṇa wants to kill his ignorance and give him real knowledge. That is also vināśāya. Vināśa, killing his ignorance. So the Bhagavad-gītā is going on for two varieties of business. One business is to give relief to the sādhu, to the devotee, and another business is to kill ignorance or kill personally the duṣkṛtinaḥ, those who are nondevotees. For them, killing business. But the killing is also good for them, because Kṛṣṇa is absolute. Either Kṛṣṇa loves somebody or kills somebody, the result is the same. That is called absolute. Just like father or mother loves some child and chastises the other, the result is the same—affection. There is no jealousy. Suppose one child is diseased, another child is healthy. The healthy child is being supplied with nice foodstuff and the diseased child, mother says: "No. You cannot eat. You go away. You get out from here." That is not that mother is unkind to the child. She is all-kind. So Kṛṣṇa's killing and Kṛṣṇa's supporting is the same. There is affection. He therefore comes here. Yadā yadā hi dharmasya glānir bhavati bhārata (BG 4.7).
Here we have come falsely to become enjoyer. Falsely. Suppose I am American or Indian. I am enjoying my life very nicely. I have got everything complete. But it is no guarantee that next life you shall become American and you will be situated in the same position. Therefore my enjoyment, so-called enjoyment, is false enjoyment. Temporary. It will not stay, because I will have to change body. I will have to change body. There is no guarantee. This is the law of nature. Duḥkhālayam aśāśvatam (BG 8.15). It is the place for miseries, and that is also temporary. If you want to make some compromise, "Never mind it is a place of miseries. I'll stay here comfortably as much as possible." But Kṛṣṇa says, aśāśvatam. Even if you make some compromise arrangement, you cannot stay here. You'll be kicked out. As soon as you think that, "Now I have got a very nice building, very nice wife and children. Everything is properly settled. Now I am happy," next day, "Get out." Finished. This is the law. Daivī hy eṣā guṇamayī mama māyā duratyayā (BG 7.14).
