Prabhupāda: . . . just like big, big tree grows. They have got intelligence, but their intelligence is supplied in a different way. And every . . . everywhere, every field of activity will require intelligence. Best intelligence is how to become Kṛṣṇa conscious. That's all. That is the best intelligence; otherwise every field of activity is requiring intelligence. Without intelligence he cannot make progress. So the best use of intelligence is to become Kṛṣṇa conscious and make life successful. That is real intelligence. Kṛṣṇa ye bhaje se baḍa catura: anyone who is Kṛṣṇa conscious, he is first-class man. That is the solution of life. Otherwise, you become very intelligent—you get some money, you get some prestige, some power—then what is that? Just after death everything is finished; it will not stay.
Then you bring in another chapter, again struggling—either human being or cat, dog or tree or like that. That is nature's law; you cannot avoid it. You are very intelligent, you have made your position very nice—that is all good. (aside) Come on. But . . . (aside) Hare Kṛṣṇa . . . if at the time of death everything is taken away, then where is your intelligence? Huh? Whatever you have got, your position now, in this body, is very good; therefore you have so much bank balance, you have got so much, how you say, so many things according to your desire, you have got it very good. But at any moment death will come and take away everything. Then what is your intelligence? (aside) Thank you. Where is your intelligence? Whatever you have got you could not keep; that you have to leave like that. Just like if you are giving me all these things, and if I know as soon as I go out of this door I cannot take this, (laughs) then what is the use? I cannot keep it.
