Why did Das Ganu go to Sai Baba in Shirdi, and what was the specific problem he was facing with the Ishavasya Upanishad?

Das Ganu's visit to Sai Baba in Shirdi, as detailed in Chapter 20, was driven by a profound challenge he encountered while working on a religious text. He had started writing a commentary called the "Ishavasya-Bhavartha-Bodhini" to explain the Ishavasya Upanishad in simple Prakrit for those who didn't know Sanskrit. However, the chapter explains that while he could translate the words, he couldn't grasp the "internal secret" or deep meaning. This lack of true understanding meant his mind "found no joy," and it was this doubt that he brought to the feet of his Satguru, Sai Baba, for resolution.
