The teachings of Bhagavad-gita, how it has to be received, that is explained here. It is not to be understood by so-called scholarship. In the Vedic literature we find, nayam atma pravacanena labhyo na medhaya na bahuna crutena. If you're actually interested in atma-jnana, self-realization, then you cannot understand by your so-called academic education. No. Nayam atma pravacanena... Or because you are a big speaker, you can speak very nicely, decorating language, therefore you have understood. That is also not possible. The spiritual knowledge has to be understood by the grace of the Supreme Spirit. Yam evaisa vrnute tena labhyah-labhyah Katha Upanisad 1.2.23. One who is favored by the Supreme... Here Krsna, the Supreme Being, God, He's explaining about Himself. So you have to learn about God, or Krsna, from Krsna, or through the parampara.
