Srila Prabhupada speaks out against Bhagavad Gita changes –
“We are therefore presenting Bhagavad-gītā as it is. We do not change.
Why should you change? What right you have got to change?”
“So if you read Bhagavad-gītā as it is, that is mad-āśrayaḥ. But if you interpret Bhagavad-gītā according to your rascal imagination, that is not Bhagavad-gītā. Therefore it is called mad-āśrayaḥ, “Under My protection, as I am tea . . .” We are therefore presenting Bhagavad-gītā as it is. We do not change. Why should you change? What right you have got to change? If Bhagavad-gītā is a book of authority, and if I make my own interpretation, then where is the authority? Can you change the law book according to your interpretation? Then what is the meaning of that law book? That is not law book. You cannot change. Similarly, if you accept Bhagavad-gītā as the book of authority, you cannot change the meaning. That is not allowed. What right? If you have got some opinion, if you have got some philosophy, you can write in your own book. Why you are, I mean to say, killing others and yourself by interpreting Bhagavad-gītā? You give your own thesis in a different way. But these people, they take advantage of the popularity of Bhagavad-gītā and interpret in a different way according to their own whims. Therefore people do not understand what is Kṛṣṇa. That is the difficulty. And the purpose of Bhagavad-gītā is to understand Kṛṣṇa. And all the so-called scholars’ and politicians’ commentary is to banish Kṛṣṇa or to kill Kṛṣṇa—the Kaṁsa’s policy. The Kaṁsa was always thinking of Kṛṣṇa, how to kill Him. This is called demonic endeavor. So that will not help you.”[27th April 1974,Lecture BG 07.01 – Hyderabad]
