Prabhupāda: What is the meaning of their radios? Do you think that their radios are perfect? Do you think so? What, Acyutānanda Mahārāja? Radio perfect? It is not perfect.
Acyutānanda: And I think the demigods and higher beings, they can disturb all their radio attempts.
Prabhupāda: No, apart from that...
Acyutānanda: Because they don't want trespassers.
Prabhupāda: ...how you can accept their radio machine are perfect? Because it is made by imperfect person, so how it can be perfect? If the manufacturer is imperfect, how he can make perfect machine? Nothing is perfect.
