We are changing our form of life from one body to another, but if we want to understand God... That is essential. So long we do not understand God, so long we do not go back to home, back to Godhead, our struggle for existence will continue. Manaḥ ṣaṣṭhānīndriyāṇi prakṛti-sthāni karṣati (BG 15.7). They struggle. Everyone struggles hard to become happy, but that is not possible. Simply searching after, searching after happiness, our time comes: "Finished. Your business is finished. Now get out." That is called death. So death is also Kṛṣṇa. Kṛṣṇa says in the Bhagavad-gītā, mṛtyuḥ sarva-haraś cāham (BG 10.34). Mṛtyu, Kṛṣṇa, comes as death. During your lifetime, if you do not understand Kṛṣṇa consciousness, this Kṛṣṇa will come as death and take away everything what you have got. Sarva-haraḥ. Then your body, your family, your country, your bank, everything business, business—finished. "Now you have to accept another body. You forget about all these things." This is going on. Bhūtvā bhūtvā pralīyate (BG 8.19).
So this Kṛṣṇa consciousness movement is the greatest benefactory movement to the human society because it is giving information to the human society that "You make your life... You have got this nice human form of body. Make this life perfect by understanding Kṛṣṇa." This is the opportunity. You may think of independent of Kṛṣṇa. You are not independent of Kṛṣṇa. You are under the rules and regulation of Kṛṣṇa, because we are under the rules and regulation of material nature. But what is this material nature? Material nature is agent of Kṛṣṇa. Mama māyā. Kṛṣṇa says, mama māyā duratyayā. You cannot surmount the stringent laws of material ways. And this māyā is Kṛṣṇa's māyā. Therefore the conclusion is given by Kṛṣṇa, mām eva ye prapadyante māyām etāṁ taranti te (BG 7.14). If you want to get out of the māyā's activities, prakṛteḥ kriyamāṇāni guṇaiḥ karmāṇi (BG 3.27), then you have to take to Kṛṣṇa consciousness. There is no way out. This is a scientific movement. Anyone, intelligent person, any thoughtful person, he must take to Kṛṣṇa consciousness. Otherwise he is doomed.
