Prahlāda Mahārāja, advising his classfriends, "My dear friend, if you want success in your life..." People do not know what is the success of life. Na te viduḥ svārtha-gatiṁ hi viṣṇum (SB 7.5.31). Everyone is supposed to be interested in his self, what is called self-interested. Everyone, beginning from the animal up to the highest living entity, Brahmā, everyone is interested for his self-satisfaction. But Prahlāda Mahārāja says, not exactly here, in other place, he has said, na te viduḥ svārtha-gatiṁ hi viṣṇum (SB 7.5.31). When he was talking with his father, father was instructing him that "You foolish boy. You are simply chanting Hare Kṛṣṇa. You do not know your self-interest. You should be politician. You should be technician. You should be bluffer. (laughter) So so many things are there. Unless you become quite alert in this world, how you can live?" The child said, "My dear father, perhaps you do not know what is your self-interest." Yes. He was always challenging his father. Five years old boy, and his father, the most powerful atheist king, and he was talking very freely. At last, when the boys was challenging always the father, the father inquired, "You rascal, under whose strength you talk with me so freely?" The boy replied, "My dear father, by whose power you are talking so freely, I am also talking by His power." (laughter) So that is the difference between atheist and theist. The child knew, "My dear father, you are so proud of your strength, of your material assets, but you do not know by whose grace you have got all these things. But I know. I know. Therefore by whose power you are so puffed up, by His power I am so humble." That is the difference. That is the difference. "The power is acting equally within you and within me, but you want to be puffed up, so He is helping you how you become more and more puffed up and go to hell." (laughter)
Kṛṣṇa says in the Bhagavad-gītā, ye yathā māṁ prapadyante tāṁs tathaiva bhajāmy aham: (BG 4.11) "Anyone who worships Me in a particular way, I give him chance to be successful in that particular way." If you want to be a first-class atheist, Kṛṣṇa will give you chance to become a first-class atheist. He will give you intelligence. He will give you ways and means how you can become a first-class atheist. And if you want to become a first-class devotee, Kṛṣṇa will give you intelligence how you can become a first-class devotee. Therefore He says, ye yathā māṁ prapadyante. If you think that Kṛṣṇa here: "Here is a statue of Kṛṣṇa. He is an idol. And these foolish people are chanting Hare Kṛṣṇa with an idol," so Kṛṣṇa will remain to such person an idol forever. And one who knows, "Oh, these people are chanting Hare Kṛṣṇa, the Supreme Personality of Godhead," for him, Kṛṣṇa will reveal, "Yes. I am the Supreme Personality of Godhead." This is the difference.
In the Bhagavad-gītā you'll find, sarvasya cāhaṁ hṛdi sanniviṣṭo (BG 15.15). Kṛṣṇa says that "I am living in everyone's heart." Sarvasya cāhaṁ hṛdi sanniviṣṭo mattaḥ smṛtir jñānam apohanaṁ ca: "And through Me one is forgetting and one is remembering." So why Kṛṣṇa is doing like that? He is helping somebody to forget, and He is helping somebody to remember. Why? The same answer: ye yathā māṁ prapadyante. If you want to forget Kṛṣṇa or God, He will give you intelligence in such a way that you will forget forever. There will be no chance to come to the precincts of God. But it is the devotees of Kṛṣṇa. They are very compassionate. Kṛṣṇa is very strict. If anyone wants to forget Him, He will give him so many chances that he will never be able to understand what is Kṛṣṇa. But Kṛṣṇa's devotee are more compassionate than Kṛṣṇa. Therefore they preach Kṛṣṇa consciousness or God consciousness to the poor people. Gṛhiṇāṁ dīna-cetasām. Mahad-vicalanaṁ nṛṇāṁ gṛhiṇāṁ dīna-cetasām. When Nārada approached Mahārāja Yudhiṣṭhira, he welcomed him that "My dear sir, you are free. You can travel anywhere you like. You are so great and so free. Then why do you come to me? You have no business to come here. I am ordinary king, and what business you have got with me? But still, you come to my house. You talk with me. Why?" Gṛhiṇāṁ
dīna-cetasām. Our mind is very poor. We simply... We are very much busy in the matter of maintaining family, and we have taken it: "This is the sum and substance or success of life."
In this way, as the other day I was speaking, not here, in San Francisco, that in this age especially, a man will think himself very successful if he simply can maintain one wife and a few children. That's all. He will think himself very successful. And actually, it is a problem for present day people to maintain even an wife, which is... An animal, an animal is also maintaining a wife. There is no difficulty for him. A dog has a wife and children, so he has no economic problem. A bird has wife and children, but he has no economic problem. But man has gone so down that he is thinking to keep wife and children is an economic problem, to avoid it. To avoid it use contraceptive method, no children, simply indulge in sex life. So man has become so down and down, especially in this age. But it is not a problem. Bhāgavata says that this is not a problem. You are thinking of maintaining your wife and children. Oh, that is already arranged. As this is arranged for the animals, for the birds, for the beasts, to have a wife and enjoy sex life and beget some children, then why not for you? You are advanced human being. Then Bhāgavata says that tasyaiva hetoḥ prayateta kovidaḥ. One who is intelligent, one who knows things as they are, he is called kovidaḥ. Kovidaḥ means very expert. So Bhāgavata advising the most intelligent man that tasyaiva hetoḥ prayateta kovidaḥ: "If you are intelligent, then you should try for advancing your Kṛṣṇa consciousness." Why? Na labhyate yad bhramatām upary adhaḥ: (1.5.18) "Because this Kṛṣṇa consciousness is so valuable and rare that if you travel all over the space by your sputnik or something else, you cannot get this Kṛṣṇa consciousness anywhere." Na labhyate yad bhramatām upary adhaḥ. "Oh, Kṛṣṇa consciousness is so very valuable that I shall simply devote my life only for attaining or achieving this end of life? Then what about my economic problem?" The Bhāgavata says, tal labhyate duḥkhavad anyataḥ sukhaṁ kālena sarvatra gabhīra-raṁhasā: "My dear friend, because you are a part and parcel of the Supreme Lord, so your economic problem is already solved." You will get something to eat, you will have some opposite sex to satisfy your senses, and you will be able to defend yourself according to your capacity, and āhāra-nidrā, and you will be allowed a place to sleep nicely. That is already arranged.
