I read that Das Ganu was struggling with a scripture. What was his project, and what advice did Sai Baba give him?

According to Chapter 20, Das Ganu was working on a commentary called the "Ishavasya-Bhavartha-Bodhini." His goal was to translate the deep meanings of the Ishavasya Upanishad into simple Prakrit (Marathi) language for those who were not familiar with Sanskrit. However, he found that a literal translation was insufficient to capture the internal secret, and his mind found no joy in the work. When he took this doubt to Sai Baba in Shirdi, Baba gave him a cryptic instruction, stating, "The resolution of this doubt of yours will be done by the maidservant at Kaka’s house when you return there."
