Prabhupāda: Of course, such description is not in the Vedas, but in some sources we can understand that one king wanted to enter the heavenly kingdom, but he was opposed. He was opposed by the demigods. So much information we have got. So those who are not fit to live there or enter there, maybe they will be opposed by the inhabitants there. And that is also natural to think. If somebody all of a sudden comes to your country, oh, there is immediately immigration department. They will see the bona fides, how you can enter? So why don't you take that also? If moon planet is inhabited by more intelligent class of living entities how do we expect that without opposition we will be allowed to enter?
Reporter: So they are said to be a more intelligent entities.
Prabhupāda: Oh yes. Oh yes. They are living ten thousand years, they are not intelligent? Their standard of living, their mode of civilization, their mode of thinking, everything is higher than this planet.
Reporter: Is this from this book?
Prabhupāda: Yes.
Hayagrīva: You say they may not be visible to us, though.
Prabhupāda: Yes.
