Just like we sometimes criticize big men. Hm? So on what strength? That strength is because we have taken shelter of Kṛṣṇa consciousness, Caitanya Mahāprabhu. Otherwise, any ordinary man can criticize. Just like the Consulate General in San Francisco, he was speaking to me that "Swamiji, you have called Maharishi a rascal?" "Yes. Yes. I may have called. What is that?" So the people, a man who is worshiped by so many people we call rascal? On what strength? The strength is this Kṛṣṇa consciousness. We can prove that he is rascal. I am not speaking; Kṛṣṇa is speaking. Kṛṣṇa says in the Bhagavad-gītā, na māṁ duṣkṛtino mūḍhāḥ [Bg. 7.15]. Mūḍha means rascal. So I am repeating Kṛṣṇa's word. Anyone who does not surrender unto Kṛṣṇa, he is rascal.
So we can quote from Bhagavad-gītā. If somebody brings case against us, so we can freely say that "I am not speaking. It is said in the Bhagavad-gītā. You just bring libel case against Bhagavad-gītā. Why you are troubling me?" (laughter) Bhagavad-gītā says anyone who does not surrender to Kṛṣṇa... Na māṁ duṣkṛtino mūḍhāḥ mām... Na māṁ duṣkṛtino mūḍhāḥ prapadyante narādhamāḥ. He's not only rascal, he's the lowest of the mankind. And if you say, "Oh, he is very learned scholar." Oh, māyayāpahṛta-jñānāḥ [Bg. 7.15]. His knowledge has been taken away by māyā. Āsuraṁ bhāvam āśritāḥ. Simply he's defying God. Kṛṣṇa means God. "I am God," that is asuric.
