What led Das Ganu to seek Sai Baba's help in Chapter 20, and what was the nature of his project?

As detailed in Chapter 20, Das Ganu was working on a project to make the profound teachings of the Ishavasya Upanishad accessible to people who were ignorant of the Sanskrit language. His goal was to create a commentary in simple Prakrit verses, which he called the 'Ishavasya-Bhavartha-Bodhini.' While he managed a word-for-word translation, he struggled because he couldn't grasp the 'internal secret' or the deep, hidden meaning of the text. This lack of true understanding caused a doubt to arise in his mind, which prompted him to travel to Shirdi to seek guidance from his Satguru, Sai Baba.
