Arjuna says, sarvam etad rtam manye yad vadasi keśava: [Bg. 10.14] “My dear Krishna, whatever you say, I accept it in total.” Without any interpretation.
But the rascals accept this Bhagavad-gita on the principle of ardha-kukkutī-nyāya. In the nyāya śāstra, there is a logic called ardha-kukkutī-nyāya. Kukkuti means the hen. The hen gives one egg every day. So the proprietor of the hen is considering that “This hen is very good. It is giving one egg every day. But its mouth is expensive. It eats. So let me cut the mouth, let me simply take the egg.” So there are rascals, who study Bhagavad-gita on this principle of ardha-kukkutī-nyāya. “Cut this, take this, cut this, take this.” The rascal does not know that if you cut the head, there will be no more production of egg. So similarly, if you try to study Bhagavad-gita according to your whims, “cut this and take this”, that is not the way to study Bhagavad-gita. That is something else.
Therefore we have to take from Arjuna how he accepted Bhagavad-gita. He said, sarvam etad rtam manye: [Bg. 10.14] “Krishna, You are the Supreme Personality of Godhead. Whatever You are speaking, whatever You have spoken, I take them as it is.” This is the study of Bhagavad-gita. [Lecture, Bhagavad Gita 2.28-29, London, July 22, 1973]
So these rascals accept śāstras like that. “Oh, this is not… That is very expensive. Cut this portion.” And when Krishna says that “Anyone who sees Me in everyone,” “Oh, that is very palatable. That is very palatable.” And when Krishna says, “You give up everything. You surrender…,” “Oh, that is not palatable.” And this is ardha-kukkutī-nyāya: I accept things which are very favorable to my understanding, and other things I reject. So the Mayavadis accept śāstras in that way. [Lecture, Srimad Bhagavatam 6.1.22, Indore, Dec 13, 1970]
There is a nonsense swamiji in India. He says, “We can take up those verses which are beneficial. Otherwise I reject.” This is called ardha-kukkutī-nyāya. [Lecture, Srimad Bhagavatam 7.9.53, Vrndavana, April 8, 1976]
Therefore we are presenting Bhagavad-gita as it is. We cannot use the ardha-kukkutī-nyāya [Cc. Adi-lila 5.176]. I take half the hen. I take the rear part, and the front part I reject. This kind of logic, argument, will not be very successful. You have to take as it is, in toto, and you have to understand. That is understanding of Bhagavad-gita. If you take something of your choice, that is useless waste of time. Just like Mahatma Gandhi, he wanted to prove nonviolence from Bhagavad-gita. How it is possible? Bhagavad-gita was spoken on the battlefield. So in this way, if we try to understand Bhagavad-gita, it will be not be Bhagavad-gita, it will be something else. We must understand Bhagavad-gita as it is. That is our preaching method. We are presenting Bhagavad-gita as it is all over the world. [Lecture, Bhagavad Gita, 13.13, Bombay, October 6, 1973]
