What was Das Ganu trying to write, and what problem did he face that led him to seek Sai Baba's help?

Das Ganu was working on a commentary called the "Ishavasya-Bhavartha-Bodhini," which aimed to explain the deep meanings of the Ishavasya Upanishad in a simple Prakrit language for people unfamiliar with Sanskrit. As detailed in Chapter 20, his problem was that although he had translated the text word for word, he felt he had not understood its internal secret or deeper meaning. This left him without any joy in his work, and this doubt is what prompted him to go to Shirdi and take the issue to the feet of his Satguru, Sai Baba.
