Why did Das Ganu seek out Sai Baba in Shirdi, and what project was he struggling with?

According to Chapter 20, Das Ganu went to Sai Baba in Shirdi because he encountered a significant doubt while working on a commentary called the "Ishavasya-Bhavartha-Bodhini." His goal was to compile an explanation of the Ishavasya Upanishad in simple Prakrit language for people who were ignorant of Sanskrit. The chapter explains that although he had completed a word-for-word translation, he felt he had not understood the "internal secret" or deep meaning of the text, and his mind found no joy in the work. It was to resolve this profound doubt that he took his problem to the feet of his Satguru, Sai Baba.
