What was the specific Gita verse that Nana Chandorkar was asked to explain, and how is it traditionally interpreted?

The verse in question, as detailed in Chapter 39, is from the Bhagavad Gita, specifically verse 4.34: "Tadviddhi pranipatena, pariprashnena sevaya | Upadeksyanti te jnanam, jnaninastattvadarsinah." Nana Chandorkar, being well-versed in Gita commentaries, explained its traditional meaning. He stated that one acquires spiritual Knowledge from the Wise (Jnanis) through three key actions: prostrating at the Guru's feet (pranipatena), asking respectful questions (pariprashnena), and dedicated service to the Guru (sevaya). This is the path Krishna advised Arjuna to follow to be instructed by those who have seen the Truth.
