What were the primary sacred books that were read in Shirdi under Baba's guidance, and what was their significance?

The main sacred texts read daily in Shirdi, as highlighted in Chapter 18, were the Bhagavad Gita and the Bhagavat, which were considered to contain the essence of the Bhagavat religion. Two specific books are emphasized: Jnandeva's Bhavartha Deepika, also known as Jnaneshwari, which is a commentary on the Gita, and the eleventh Skandha of the Bhagavat, referred to as the Nath Bhagawat. The Nath Bhagawat, a dialogue between Krishna and Uddhava, was held in particularly high esteem, described as being even better than the dialogue between Krishna and Arjuna. Baba considered these divinely inspired books and ensured they were read daily by devotees like Bapusaheb Jog to help others attain their highest spiritual goal.
