What was the primary motivation behind Das Ganu's project, the 'Ishavasya-Bhavartha-Bodhini,' and what was the nature of his struggle?

As detailed in Chapter 20, Das Ganu's primary motivation for creating the 'Ishavasya-Bhavartha-Bodhini' was to make the profound teachings of the Ishavasya Upanishad accessible. He intended to compile an explanation in simple Prakrit language, using Ovi verses, specifically for those who were 'ignorant of the Sanskrit language.' His struggle was not one of simple translation; he successfully translated the text word for word. The real difficulty lay in his inability to comprehend and convey the 'internal secret' and deep spiritual meaning, which left him feeling that his work was incomplete and without joy.
