What was the name and purpose of the literary work Das Ganu was creating, as mentioned in Chapter 20?

As detailed in Chapter 20, the work Das Ganu had undertaken was titled the 'Ishavasya-Bhavartha-Bodhini.' Its purpose was to serve as a commentary that would elaborate on the meaning of the Ishavasya Upanishad for people who were ignorant of the Sanskrit language. He aimed to compile an explanation using simple Prakrit language in Ovi verse form, making the profound scriptural text accessible to a wider audience. However, he faced a block when he couldn't understand the text's deeper meaning himself.
