So our business is, Kṛṣṇa consciousness movement is that we have to satisfy Kṛṣṇa. That reference by that Professor Zaehner, that one rogue, he did by his whims, and he alleged that "After reading Bhagavad-gītā violence, he committed this violence." So did he take permission from Kṛṣṇa or Kṛṣṇa's representative? But he does not know the technique. He has unnecessarily accused, committed a great offense to the lotus feet of Kṛṣṇa. So therefore inexperienced persons, they should not try to teach Bhagavad-gītā to others because he has no knowledge. This knowledge has to be received by paramparā system. Evam paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). So simply by academic career, by knowledge of ABCD, you cannot understand Bhagavad-gītā. In the Bhagavad-gītā it is said, bhakto 'si priyo 'si me (BG 4.3), without becoming bhakta... Therefore Sanātana Gosvāmī has forbidden that "Don't hear anything about Kṛṣṇa from a person who is not a Vaiṣṇava." Avaiṣṇava-mukhodgīrṇa-pūta-hari-kathāmṛtaṁ śravanaṁ na karta... This is prohibited. You cannot hear. But this audience or the students, they also do not know that "Here is a rascal, he is not a devotee, he is not a Vaiṣṇava. Why shall we hear from him Bhagavad-gītā?" The first condition is bhakto 'si. And the prohibition is also by ācāryas. Avaiṣṇava-mukhodgīrṇa-pūta-hari-kathāmṛtaṁ śravanaṁ na kartavyam. Pūta-hari-kathāmṛtam. Hari-kathā, talks of Kṛṣṇa, they are by themselves pure. But still, it is prohibited that if it is spoken by an avaiṣṇava, nondevotee, one should not hear, should not hear. Must immediately reject. First of all, we have to see who is going to speak about Kṛṣṇa. Is it a devotee of Kṛṣṇa? Is he a Vaiṣṇava or not? If he is not, then immediately reject: "Oh, we are not going to hear from you." But people do not know. Any rascal speaking about Bhagavad-gītā we hear. That is not the process. Then you will misunderstand. Avaiṣṇava-mukhod..., sarpocchiṣṭaṁ payo yathā. Just like milk is very good food, everyone knows. But when it is touched by the tongue of the serpent, it is poison immediately. So we cannot drink poison. Don't hear Bhagavad-gītā or any talk about Kṛṣṇa from a person who is not a Vaiṣṇava, who is not a devotee of Kṛṣṇa. We'll misunderstand.
