I read that Das Ganu had a problem related to a scripture. What was the specific issue he faced, and what was Sai Baba's initial advice?

Chapter 20 explains that Das Ganu was writing a Marathi commentary on the Ishavasya Upanishad, titled "Ishavasya-Bhavartha-Bodhini." His problem was that while he could translate the scripture word for word, he couldn't grasp its deep, internal meaning, and his mind found no joy or satisfaction in the work. When he took this doubt to Sai Baba in Shirdi, Baba gave him a cryptic response. Instead of explaining it Himself, Baba told Das Ganu, "The resolution of this doubt of yours will be done by the maidservant at Kaka’s house When you return there."
