How does the narrative in Chapter 39 emphasize Sai Baba's profound scriptural knowledge despite his lack of formal training?

Chapter 39 highlights Baba's innate spiritual wisdom by questioning how he could be the 'knower of the heart of the Gita's meaning' without having formally studied Sanskrit or the scriptures. The text suggests that the 'knowledge of Saints is beyond reach.' The story serves as proof of this idea. Baba doesn't ask Nana about the verse for his own learning; rather, he initiates the dialogue 'so that the true teaching would be impressed upon Nana.' By posing the question and steering the conversation, Baba demonstrates a masterly and intuitive grasp of the Gita's essence that transcends conventional, scholarly learning, revealing his divine insight.
