Prabhupāda: My authority is Vedic literature, yes. You'll find Bhagavad-gītā... You have seen our book Bhagavad-gītā?
Journalist: Yes. We have it at the office. I've seen it.
Prabhupāda: There are descriptions. There are descriptions of these things. There is description of another nature which is called spiritual nature. This is material nature. The sky, as far as you can see, this is one universe. Similarly, there are millions of universes. And all these together, that is material sky. And beyond that, there is spiritual sky, which is far, far greater than this. And there are spiritual planets. So this information we have got from Bhagavad-gītā, what to speak of other Vedic literatures. Bhagavad-gītā, it is daily read by practically all over the world, but they do not understand it. Simply they become student of Bhagavad-gītā, or simply just to think falsely that "I am God." That's all. But they don't take any particular information. There is a verse in the Eighth Chapter, paras tasmāt tu bhāvo 'nyo 'vyakto 'vyaktāt sanātanaḥ (BG 8.20). There is another nature beyond this material nature which is eternal. This nature is coming into existence, again dissolution. But that nature is eternal. These things are there. Similarly, there, planets are also eternal. There, living entities, they are also eternal. That is called sanātana. Sanātana means eternal, without any end, without any beginning. But this nature, as we have, this body has got a beginning and it has end, similarly anything, this cosmic nature has a beginning and it has an end. So our this Kṛṣṇa consciousness movement is how to transfer our self to that nature, eternal nature.
Journalist: That's man's quest.
Prabhupāda: Yes. That is the quest. Everyone is trying to be happy because that is every living entity's prerogative. He is by nature to become happy but he does not know where to become happy. He's trying to become happy where four things are, miserable conditions are there, namely birth, death, disease, and old age. So many scientists, they are trying to become happy, to make people happy, but which scientist has tried to stop death, to stop old age, to stop disease? Has any scientist tried?
Journalist: I don't know.
