What was Nana Chandorkar's traditional explanation of the Gita verse that Sai Baba asked him about?

Nana Chandorkar, being an expert in Gita commentaries, provided a conventional interpretation of the verse. As described in Chapter 39, Nana explained with humility that the verse instructs a seeker to attain knowledge from the Wise by performing three actions: prostrating at the Guru's feet, serving the Guru with one's life, and asking respectful questions. He summarized that Lord Krishna's message to Arjuna was that service to the Guru and prostration are the primary methods for receiving Knowledge, and by following this path, the Wise who have seen the Truth will guide the seeker.
