Prabhupāda: (aside:) Keep Bhagavad-gītā in hand, yes. That's it.
Guest (Hṛdayānanda): So he is saying that this material world is a combination of so many different elements, intelligence, so on and so forth. And in the center of all of this, the essence is that which is eternal. And this eternal thing cannot have any name because then it would be limited, and that would be a contradiction. And also it has no form.
Prabhupāda: No, that eternity, that is nice, that the material world is temporary, and the eternity is spiritual. That is clear understanding. Material elements, just like earth, water, fire, air, sky, mind, ego, intelligence, and the spiritual element is which is utilizing these material elements. Do you admit this?
Guest: Si.
Prabhupāda: The others? That is the distinction between matter and spirit. Just like this microphone, it is combination of earth, water, air, fire, like that. But the living being, he has utilized, he has combined this matter into this microphone. Is that admitted? Now, exactly like the microphone, the combination of matter and done by some living entity, similarly, the whole cosmic manifestation is combination of matter, and there is one living being or the Supreme Being who has combined them, and it is working. Is that admitted? So that is the difference between limited and unlimited, that I, you are living being... We can also create something like this microphone or this big aeroplane. We have created. That is limited. But there is another one who has created innumerable planets and that is floating in the air. Is it not? We are taking credit of becoming big scientist by creating one airship, 747, five hundred passengers carrying. How many we have created? Maybe hundred, two hundred. But there are millions and trillions of planets floating in the same way in the air, and those planets containing so many big, big mountains, ocean, and they are floating in the air. We can create limited things, but He can create unlimited things. Therefore we have got our limited brain, and He has got unlimited brain.
