Prabhupada: Nobody says, "Here is God." That is, perhaps... We Vaisnavas say; I am preaching. Perhaps I am the first preacher to the world, that "Here is God."
Dr. Patel: Some of these great Vaisnava acaryas were doing interpretation of Bhagavad-gita...
Prabhupada: The who is acarya except the Vaisnava acarya? All loafer class. All loafer class. They're not acaryas. Except these Vaisnava acaryas, who is acarya? They're not acaryas. Acaryam mam vijaniyan (SB 11.17.27).
Dr. Patel: I read your Bhagavad-gita, and after that, I read Ramanuja's. They more or less the same...
Prabhupada: Same thing. There is no difference between the acaryas. Then how he becomes acarya if there is difference of opinion? They cannot be acarya.
