Acyutānanda: "When you said that everyone is destined to a particular goal, then where is the question of preaching Kṛṣṇa consciousness?"
Prabhupāda: Therefore I said, tasyaiva hetoḥ prayateta ko. . . You should try only for Kṛṣṇa consciousness; other things are destined. That is my. . . You did not hear properly, that you should not try for anything else, because that is already destined. If you want success, then simply try for Kṛṣṇa consciousness. That is wanted. Tasyaiva hetoḥ prayateta kovido na labhyate yad bhramatām upary adhaḥ (SB 1.5.18). We did not try in our other life. Other than human life, we did not try it. We simply tried for eating, sleeping, mating and defending. Animal life. If you do the same thing again, and do not take to Kṛṣṇa consciousness, then you are losing your time. Therefore it is advised, you should try only for Kṛṣṇa consciousness, not for other things. They are already destined. This is the instruction.
Acyutānanda: "What would be the result if all the people became devotees of Kṛṣṇa Caitanya Mahāprabhu?"
Prabhupāda: Very good result. He is lamenting, that he doesn't want this good result that everyone will become Kṛṣṇa consciousness? Eh? There is a story in this connection that there was a haṭṭa, a fair or market. So many people came there, and one old lady began to cry, "Where shall I give them place? So many people have come here." She began to cry. Then her son said, "My mother, see in the evening. You don't worry about giving them place." So in the evening she saw everyone has gone. Similarly, in due course of nature's activities, prakṛteḥ kriyamāṇāni guṇaiḥ karmāṇi sarvaśaḥ (BG 3.27), everything will go nicely. You haven't got to be worried. You better be worried how to develop your Kṛṣṇa consciousness. Other things will go on. And what is the harm there? If all people become Kṛṣṇa conscious and go back to home, back to Godhead, what is the harm there? Do you mean to say, to remain here in this material existence and suffer three-fold miseries, is that very good business? That will not happen. Don't be worried. Kṛṣṇa consciousness is not so cheap. Only a few fortunate people will take it. Others will remain. Don't worry. (laughter)
Acyutānanda: "How is that there are different types of religions in the world?"
Prabhupāda: There is no religion. This is manufactured religion. Real religion is to surrender to Kṛṣṇa, sarva-dharmān parityajya (BG 18.66). Therefore it is advised that you give up all these so-called religions, sarva-dharmān. You become surrendered to Kṛṣṇa. That is real religion. All others, cheating religion, that's all. Dharmaṁ tu sākṣād bhagavat-praṇītam (SB 6.3.19). Just like there may be so many laws, but the real law is what is given by the government. Similarly, there may be so many so-called religious system, but the real religious system is what is spoken by God Himself. That is real.
