What was the initial context that led to Sai Baba asking Nana Chandorkar for the meaning of the Gita verse?

The dialogue was initiated by Sai Baba himself in a seemingly casual moment. According to the account in Chapter 39, Baba heard Nana Chandorkar 'humming' or 'muttering under his breath.' Seizing this as a teaching opportunity, Baba paused and commanded Nana to recite the verse clearly and slowly so it could reach his ears. The text explicitly states that Baba's intent in asking for the verse and its detailed explanation was to impress the 'true teaching' upon Nana. Therefore, the context was not a formal discourse, but a spontaneous moment that Baba purposefully transformed into a profound lesson on the path to knowledge.
