Can you explain the interaction between Sai Baba and Nana Chandorkar regarding the Bhagavad Gita and how it relates to intellectual pride?

Chapter 50 recounts an incident where Nana Chandorkar was quietly reciting the Bhagavad Gita. Baba, noticing his muttering, engaged him in a dialogue. After Nana recited and explained a verse according to traditional commentators, Baba playfully challenged his understanding. As described in Chapter 50, Baba asked Nana to consider an alternative interpretation of a line, suggesting the word 'jnanam' (knowledge) could be read as 'ajnanam' (ignorance). This act was not to dismiss established commentaries but to break Nana's potential intellectual pride and show that there are deeper layers of meaning beyond conventional understanding. It was a lesson in humility and open-mindedness.
