The source material emphasizes the importance of specific scriptures. Can you elaborate on the significance of the Nath Bhagavat and Jnaneshwari?

Chapter 18 highlights the supreme importance of two main books in the Bhagavat religion. The Nath Bhagavat, specifically the eleventh Skandha, is described as a divinely inspired book containing the dialogue between Krishna and Uddhava, which is considered even better than the Krishna-Arjuna dialogue. It is called the 'loving speech of Nath,' and it was believed that those who perform the reading with faith attain God instantly. The other key text was Jnandeva's Bhavartha Deepika, also known as Jnaneshwari, which is a commentary on the Gita. The merciful Sainath ensured these books were read daily in Shirdi for the spiritual upliftment of all.
