What was Nana Chandorkar's interpretation of the Gita verse he discussed with Sai Baba?

Nana Chandorkar, being very learned in Gita commentaries, explained the verse with great humility. As detailed in Chapter 39, he stated that the path to knowledge involves three key actions directed towards a Guru. He explained, "By prostrating at the Guru's feet, by serving the Guru with one's life, and by respectful questioning, the Wise ones will instruct you in Knowledge." Nana summarized this as Lord Krishna's message to Arjuna, emphasizing that service and prostration to the Guru are the means by which the Wise, who have seen the Truth, will show one the path of Knowledge. He noted that this interpretation was in line with many famous commentators like Shankara and Sridhari.
