"If you prepare yourself... Just like in childhood, boyhood, if you prepare yourself, nicely educated, then you get nice job, nice situation; you will be happy. Preparation for the next life. Similarly, if you prepare yourself in this life for going back to home, back to Godhead, then where is perplexity? There is no perplexity. 'I am going to Kṛṣṇa. I am going back to home, back to Godhead. Now I will have not to change material body. I will have my spiritual body. I shall now play with Kṛṣṇa, dance with Kṛṣṇa, eat with Kṛṣṇa.' This is Kṛṣṇa consciousness movement. This is Kṛṣṇa consciousness. Prepare yourself for the next life. The man, dying man, cries because maybe he is dreaming next life horrible life. Because according to karma... Those who are very, very sinful, they cry, because they see horrible scenes at the time of death, and he is going to accept some type of body... But those who are pious, those who are devotees, they are dying without any anxiety. They are dying... The death may take place...
The example is given that... Foolish people may say that 'You devotees, you are dying, and the sinful men, or nondevotees, they are also dying. So where is the difference?' No, there is difference. There is difference. This has been described by the example: just like a cat catches its cub and catches the mouse. So formerly we see that the cat has caught the mouse in the mouth and the cub also in the mouth, but there are difference of catching. The cub is feeling pleasure: 'My mother is carrying me.' And the mouse is feeling death knell: 'Oh, now I am going to die.' This is the difference. So although a devotee is dying and nondevotee is dying, there is difference of feeling at the time of death, like the mouse and the cub. Don't consider that both of them are dying in the same process. The process may be same, but the situation is different.
Tyaktvā dehaṁ punar janma naiti mām eti kaunteya (BG 4.9). The formula is there. Kṛṣṇa says, janma karma me divyaṁ yo jānāti tattvataḥ. Simply if you try to understand what is Kṛṣṇa, divyam. They are all divine, transcendental. Kṛṣṇa's activities, Kṛṣṇa's appearance, Kṛṣṇa's worship, Kṛṣṇa's temple, Kṛṣṇa's glories—everything transcendental. So if one understands these things or tries to understand, even he does not understand, tries to understand, then he becomes liberated from this process of birth and death. Kṛṣṇa says. So become very serious to understand Kṛṣṇa and remain in Kṛṣṇa consciousness. Then this problem, birth, death, old age and disease will be solved, automatically, very easily. There will be no problem.
That is the function of the human life, to understand that 'I am eternal.' Kṛṣṇa says that 'In the past we existed, in the present we are existing, and in the future we shall continue to exist.' Then why I have got this type of body by which I am actually, not actually, superficially I am not existing? So this is the problem. A dhīra means a sober man will think of this problem, that 'I want to live. Why death takes place? I want to live very healthy life. Why disease comes? I don't want to become old man. Why old age comes?' Janma-mṛtyu-jarā-vyādhi (BG 13.9). These are the problems. So solve this problem simply by taking to Kṛṣṇa consciousness, simply by understanding Kṛṣṇa. And for understand Kṛṣṇa, the Bhagavad-gītā is there, so nicely explained.
So make your life successful, that 'I am not this body.' Simply by understand... 'I am not this body. I am embodied within this body, encaged. But I am not this cage.' Just like a bird is within the cage. The cage is not the bird. But foolish persons, they are taking care of the cage, not of the bird. The bird, out of starvation, is suffering. So we are suffering spiritual starvation. Therefore nobody is happy in this material world. Spiritual starvation. Therefore we see in an opulent country like America, enough food, enough residence, enough material enjoyment, still they are becoming hippies, all over the world. They are not satisfied, because it is spiritual starvation. Materially we may be very opulent, but if you starve spiritually, you cannot be happy. This is the process.
So spiritual rejuvenation required. Ahaṁ brahmāsmi: 'I am not this body. I am Brahman, spiritual soul.' Then you will be happy. Brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati (BG 18.54), samaḥ sarveṣu... Then there will be equality, fraternity, brotherhood. Otherwise it is all bogus, simply high-sounding words. There cannot be all these things. Come to the spiritual platform, brahma-bhūtaḥ prasannātmā na śocati na... (BG 18.54), samaḥ sarveṣu bhūteṣu. Then you can see equally. Otherwise you will see that 'I have become human being. I have got my hands and legs, and the poor cow has no hands and legs. Kill him and eat.' No. Samaḥ sarveṣu bhūteṣu. Asamata. Unequality. Why? What right you have got to kill another animal? Because you have no vision of equality, for want of Kṛṣṇa consciousness. Therefore so-called education, culture, fraternity, in this material world, all these are bogus, humbug. Simply Kṛṣṇa consciousness is the right subject matter to be studied by sane, sober, dhīra. Then the society will be happy; otherwise not."
