I heard Das Ganu had a problem writing about a scripture. What does Chapter 20 say about this story?

Chapter 20 explains the story of Das Ganu and his work on the Ishavasya Upanishad. He was attempting to create a commentary, the 'Ishavasya-Bhavartha-Bodhini,' in simple Prakrit language for those who didn't know Sanskrit. However, as noted in the chapter, he found that a word-for-word translation was not enough to grasp the deep internal meaning, and his mind found no joy. When a specific doubt arose, he took it to Sai Baba in Shirdi. Baba's response was intriguing; He told Das Ganu that the doubt would be resolved by the maidservant at Kaka’s house upon his return.
