What specific holy books were read in Shirdi at Baba's instruction, and what was their significance?

According to Chapter 18, the daily readings arranged by Sai Baba focused on two main books that form the essence of the Bhagavat religion: the Bhagavad Gita and the Bhagavat. More specifically, the texts being read were the Jnaneshwari, which is a commentary on the Gita also known as Bhavartha Deepika, and the beautiful eleventh Skandha of the Bhagavat by Eknath. These were considered a platform for achieving the highest spiritual goal. Baba's insistence on these readings demonstrated the immense value He placed on them for the spiritual development and welfare of His followers.
