Paramahaṁsa: Well, they say that this body is more complicated than any other machine because it can think, feel and will, whereas other machines, they don't do that.
Prabhupāda: But the thinking, feeling, the brain is there. If the . . . that is the particular machine, because the operator is within. That you cannot see. The thinking, feeling is coming from the operator. The soul is there, dehino 'smin yatha dehe (BG 2.13). That these rascals cannot understand, that the thinking, feeling, that is of the operator, not of the machine. Is it clear or not? The operator is within. So the thinking, feeling, as you were asking, that is not of the machine but of the operator, the soul.
Gaṇeśa: Just like the child, Śrīla Prabhupāda, who was trying to find the sound within the drum, the material scientists, they are trying to find out the cause and effect of the material world. Is that not intelligence?
Prabhupāda: Yes, but they have not reached the ultimate goal.
Paramahaṁsa: But they are trying.
Prabhupāda: They are trying. That is admitted. But they are concluding that there is no operator. That is their foolishness, because they have failed to find out. They have to go further, further, and see, "Yes, there is operator." That is the final part of the intelligence. That is stated in the Bhagavad-gītā: bahūnāṁ janmanām ante jñānavān mām (BG 7.19). So after many, many births of sincere inquiry, when he is actually intelligent, he will see, "Oh, vāsudevaḥ sarvam iti (BG 7.19). Here is Vāsudeva. He is everything." That is stated. He'll enquire, go on enquiring, life after life. And then he'll come to understand vāsudevaḥ-sa mahātmā su-durlabhaḥ. You did not read this verse?
Gaṇeśa: Oh, yes.
Prabhupāda: They will come. After much trouble, much enquiry, they will come to the same conclusion, vāsudevaḥ sarvam iti (BG 7.19). But they'll waste time. That's all. When we say, "Here is operator," they will not take. But they'll waste time, and life after life laboring, one day they will come.
