Bhagavad-gita Lecture 10.2-3 — New York, January 1, 1967 Jnane prayasam udapasya namanta eva and san-mukharitam bhavadiya-vartam.
San-mukharitam means just try to hear about the glories of the Supreme Lord from the mouth of realized souls. Don't go to the unauthorized persons.
Now, how you can know what is the difference between unauthorized and authorized?
That you can know also. There is description. That, in Bhagavad-gita you'll see, who is authorized, who is not authorized.
The Lord says, evam parampara-praptam imam rajarshayo viduh [Bg. 4.2]. This authority is handed over by disciplic succession.
Bhagavad-gita Lecture 13:22 — Hyderabad, August 17, 1976 There is no use of interpretation. Interpretation is required when you cannot understand one statement. In the law court if one statement is ambiguous then two parties argue on it. "I think it is this," "I think…" But when it is clear there is no question of interpretation. Unfortunately the Bhagavad-gita is being interpreted by unauthorized persons unnecessarily, and people are kept into darkness.
We are trying to protest against this process.
Srimad-Bhagavatam Lecture 1.2.9-10 — Delhi, November 14, 1973 So everything is there. If we actually want to make our life perfect, the directions are already there in our… We have got the Vedic knowledge, treasurehouse of spiritual knowledge, and the Bhagavad-gita is the gist, is the summary. Gitopanishad. It is called Upanishad.
If you simply study Bhagavad-gita as it is, without foolishly interpreting it… That will spoil. Don't interpret. Just like you are given paramanna, or kshira. Everyone knows what is kshira, milk and rice cooked together with sugar, very nice foodstuff. But if you add with it several grains of sand, it becomes useless.
You can add it, simply a few grains of sand — we spoil Bhagavad-gita. Therefore Sri Sanatana
Gosvami has advised how to save yourself from this rascaldom.
He says, avaishnava-mukhodgirnam putam hari-kathamṛtam, shravanam naiva kartavyam.
Putam hari-kathamṛtam. Hari-katha. Krishna is speaking Bhagavad-gita; therefore it is called hari-katha, Krishna-katha.
So Sanatana Gosvami says, "If it is uttered by avaishnava, who is not a devotee, he is a professional man, so-called scholar and politician, don't hear it. Don't hear it."
Avaishnava: "Because he is not a Vaishnava." Avaishnava-mukhodgirnam putam hari-katha.
Hari-katha means Krishna’s words. They are very purified. That's all right.
But shravanam naiva kartavyam. Why? Because sarpocchishtam yatha payah. Just like milk.
Milk is very good food, but if it is touched by the tongue of a serpent, it becomes poison.
If you eat that kind of milk, your life will be finished. Similarly, our only request is that don't try to read Bhagavad-gita commented by unauthorized so-called scholars or politicians.
Simply read Bhagavad-gita as it is. Simply accept what Krishna says. Then you will be benefited.
SB 3.24.12 Purport – Brahma praises Kardama because he carried out the orders of the spiritual master in toto and without cheating. A conditioned soul in the material world has the disqualification of cheating. He has four disqualifications: he is sure to commit mistakes, he is sure to be illusioned, he is prone to cheat others, and his senses are imperfect.
But if one carries out the order of the spiritual master by disciplic succession, or the parampara system, he overcomes the four defects.
Therefore, knowledge received from the bona fide spiritual master is not cheating. Any other knowledge which is manufactured by the conditioned soul is cheating only…
