Puṣṭa Kṛṣṇa: What is the quality of a person who is actually faithful?
Prabhupāda: He's accepting eagerly Bhagavad-gītā if he's really follower of God. Because there is nothing extraordinary in the Bhagavad-gītā. It is the words actually for God to speak. You may call Kṛṣṇa or otherwise, but.... Just like sarva-dharmān parityajya mām ekam [Bg. 18.66]. This can be said by God only. Otherwise who can say that "You give up everything; surrender unto Me"? It can be said by God only. Either you talk of Hindu or Muslim, but ask one that "If God says, 'You surrender unto...,' will you refuse?" Let him become Muslim or Christian. So nobody can refuse the order of God. That is faithfulness.
Guru-kṛpā: Śrīla Prabhupāda, why are there so many pseudo religions then?
Prabhupāda: There is no religion! This is the only religion.
Guru-kṛpā: Then why do they mingle at all? Why do they even get involved?
Prabhupāda: Therefore we say that one who has no faith in God, he's a rascal, miscreant.
Guru-kṛpā: But they pretend.
Prabhupāda: Pretend? Kick them! Why you should accept pretension? Then you are a fool also. You say "pretend," and still, you have to talk about them. That means you are also faithless. Why should you talk about the pretension? Pretension is pretension. That is faithlessness. Sometimes they pretend honest, but he's a thief. What is this philosophy? Thief is thief. That's all.
