Which specific books were considered most important for the daily readings that took place in Shirdi?

The texts from Chapter 18 identify two main books central to the spiritual practice in Shirdi: the Bhagavad Gita and the Bhagavat. More specifically, the daily readings consisted of the 'Jnaneshwari', also known as 'Bhavartha Deepika', which is a revered commentary on the Gita, and the 'Nath Bhagawat,' which is the beautiful eleventh Skandha of the Bhagavat. These two texts, representing the essence of the Bhagavat religion, were read daily in Sathe's Wada at the merciful Sai Baba's direction for the highest spiritual goal of the devotees.
