What is the significance of Baba asking Nana Chandorkar to speak the Gita verse aloud instead of muttering?

When Baba asked Nana to speak the Gita verse aloud, it served multiple purposes. Nana was muttering to avoid disturbing others, an act of consideration. However, Baba's intervention, as described in Chapter 50, was a teaching moment. By asking him to speak clearly and questioning if he truly understood the meaning, Baba was drawing Nana out of his private recitation into a direct engagement with the Guru. This public declaration and subsequent discussion, detailed in Chapter 50, allowed Baba to test Nana's understanding and then challenge his intellectual framework, ultimately deepening his insight and demonstrating that spiritual practice isn't just a secret, internal affair.
