Our business is not very difficult. Our business is very easy because we are not manufacturing knowledge like the rascals. "I think." What you are, you are thinking like this? You are rascal number one, and you are thinking? What is the meaning of your thinking? We reject immediately. "I think." "It is my opinion." This is going on. Big, big scientists, big, big philosophers. We don't accept. We must see whether he has received knowledge from Kṛṣṇa. And one who receives knowledge from Kṛṣṇa...
Just like Arjuna. Arjuna said to Kṛṣṇa, śiṣyas te 'haṁ śādhi māṁ prapannam: (BG 2.7) "My dear Kṛṣṇa, the perplexity which has arisen in my mind, it cannot be solved by anyone except Yourself." Because Arjuna knew that Kṛṣṇa is the Supreme Personality of Godhead. Therefore he surrendered to Him. He surrendered. He was talking like friend. Friendly talking cannot give any good result, simply waste of time. But when there is talking between disciple and the spiritual master, that has got meaning.
Just like my disciples, because they have accepted me as guru, whatever I say, they accept it. Otherwise I have not bribed them. These European, Americans... I have no money. I went to New York with seven dollars. What money I have got? But they have accepted. So this is the process. You must find out somebody whom you can accept as guru. That guru must be bona fide. Otherwise what is the use of accepting a bogus guru? So what is that bona fide guru? That bona fide guru means one who has accepted Kṛṣṇa as guru. He is bona fide guru. That is bona fide guru.
Evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). Imaṁ vivasvate yogaṁ proktavān aham avyayam (BG 4.1). Kṛṣṇa says that "This system of yoga, as it is described in the Bhagavad-gītā, was first of all described by Me to the sun-god." Imaṁ vivasvate yogaṁ proktavān aham avyayam, vivasvān manave prāha: (BG 4.1) "And the sun-god again handed over the knowledge to his son Manu." Manur ikṣvākave 'bravīt: "And Manu explained the same thing to his son Ikṣvāku." Evaṁ paramparā-prāptaṁ rājarṣayaḥ (BG 4.2). So that means the knowledge is actually coming from Kṛṣṇa.
In the beginning of Śrīmad-Bhāgavatam it is also stated, tene brahma hṛdā ādi-kavaye (SB 1.1.1). Ādi-kavi is Lord Brahmā, and brahma means the Vedic knowledge. So there was nobody to teach Brahmā. Brahmā is called prapitāmaha (BG 11.39), the first-class knower of the Vedic knowledge, ādi-kavi. But wherefrom he got the knowledge? He got the knowledge form Kṛṣṇa. Tene brahma hṛdā ādi-kavaye. And Brahmā distributed it to Nārada. Nārada distributed it to Vyāsadeva. Vyāsadeva distributed it to other ācāryas. In this way, evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). So there is paramparā. The knowledge is the same. There is no alteration. But it is coming through disciplic succession, one after an... So one who receives the knowledge from the disciplic succession...
Just like at the present moment we see that Kṛṣṇa and Arjuna, they are talking. Arjuna is direct disciple of Kṛṣṇa. So if you take Bhagavad-gītā as it was understood by Arjuna, then you get the right knowledge. And if you take the knowledge of Bhagavad-gītā explained by some so-called scholar and politician, then it is rascaldom only. It has no meaning. It has no meaning.
