Why was Das Ganu struggling with his work on the Ishavasya Upanishad, and what is presented as the solution to his problem?

Das Ganu was attempting to create a simple Prakrit translation of the Ishavasya Upanishad, but he found that a word-for-word translation failed to capture its deep internal secret, leaving his mind without joy. As detailed in Chapter 20, the source explains that the Upanishads, which are the essence of the Vedas, are incredibly difficult to grasp without the grace of a Guru. The text explicitly states that even a scholar's best efforts are futile without this grace, as the hidden truth is difficult to find at every step. The ultimate solution presented is devotion to a Guru's feet, which makes the path easy and allows the hidden meaning to open up automatically. For Das Ganu, it was Sainath's grace that made the difficulty of his task vanish.
