Press man: Do you know how many followers there are in the United States now?
Prabhupāda: Unlimited. (devotees roar) Some of them admit and some of them do not admit. That's all. (laughter) Everyone is eternally servant of God, but some of them admit and some of them do not admit. That is the difficulty. But anyone who does not admit, he is servant of somebody. That is a fact. He cannot be master. Everyone is servant. But one who knows that "I am servant of Kṛṣṇa," his life is perfect. That's all.
Please try to understand this point that everyone is servant. Even your president is servant of the nation. So nobody can say that "I am no one's servant." He is servant, but he does not know that actually he is the servant of the Supreme Lord. That is his ignorance. We are just eradicating this ignorance, that "You are servant, but you admit that you are servant of God. That will make your life successful." That's all. Therefore I say that there are unlimited followers. Some of them admit and some of them do not admit. That is the difficulty. But if anyone comes to me, I shall make him to admit. Yes. (devotees roar) Hare Kṛṣṇa.
