What specific religious books did Sai Baba emphasize for his devotees to read, and what was their significance?

According to chapter 18, Sai Baba strongly encouraged the reading of several divinely inspired books for the salvation of souls. The main texts mentioned are the 'Uddhava Gita,' which is described as even better than the dialogue between Krishna and Arjuna, and the 'Jnaneshwari,' also known as 'Bhavartha Deepika.' These two, along with the 'Bhagavat' (specifically the eleventh Skandha, referred to as Nath's platform for the highest spiritual goal), were considered the essence of the Bhagavat religion. Baba believed that those who performed the reading with faith could attain God instantly and had them read daily in Shirdi.
