Based on the text, what was the spiritual significance of the Jnaneshwari and the Nath Bhagawat, and why did Baba consider them so important?

The source material in Chapter 18 portrays the Jnaneshwari (Bhavartha Deepika) and the Nath Bhagawat (Uddhava Gita) as profoundly important, divinely inspired books. The Nath Bhagawat is described as containing the loving speech of Nath (Krishna's instruction to Uddhava), which is considered even better than the dialogue between Krishna and Arjuna. Baba taught that one did not need to retreat to a forest, as God manifests in this text, and those who read it with faith could attain God instantly. The Jnaneshwari, a commentary on the Gita, and the Nath Bhagawat were seen as the essence of the Bhagavat religion. Baba's insistence on their daily reading in Shirdi underscores his belief that these texts were essential tools for the salvation of souls.
