Prabhupāda: Why shall I find out petrol, when my petrol will be finished and I'll have to take a body like a dog or a cat? (laughter) They have no such knowledge.
Hanumān: No, they don't.
Prabhupāda: So finding out the petrol . . . when his personal petrol will be finished, he will have to accept the body of a dog. That's all. What he is going to do? First of all try to fill up your own personal petrol. Their personal petrol, it is sure to finish. That they don't care. So after finishing the personal petrol, if he is going to accept the body of a dog, then what is the use of finding petrol in moon planet?
What is the answer for this, that how they are going to stop the petrol, which is going to finish after ten years or fifteen years? Where is the provision? Where is the atomic energy or petrol to keep yourself, to find out petrol in the moon planet? Where is that problem solved? By the time you find out petrol in moon planet, your petrol will be finished. (laughter) Then what you will do? Just see? Foolish attempt.
Śyāmasundara: There is no possibility of petrol on the moon.
Prabhupāda: Eh?
Śyāmasundara: Moon planet there cannot be petrol.
Prabhupāda: Unless, suppose they're making research, find out petrol on the moon planet. But say it takes forty to fifty years: by that time your personal petrol will be finished. You cannot move; you cannot stop all nonsense. Then what you will do?
So long you have got petrol, you are talking all nonsense as scientist. But when this petrol will be finished, you will no longer be able to talk even, what to speak of finding out petrol in moon planet. Where is that problem is solved? They are not very much interested in this subject matter. Eh?
After all, your petrol is limited. Suppose you can live fifty or sixty years—upmost hundred years. But the scientist, when his petrol is finished, he is kicked out on the street, many, many scientist. So why do they not find out petrol for himself, so that he may continue the research work? So why they're lacking this knowledge?
