The daily spiritual practices in Shirdi, guided by Sai Baba, centered around the reading of two main books: the Bhagavad Gita and the Bhagavat. Chapter 18 explains their significance in detail. Specifically, the texts read were the commentary on the Gita called Jnaneshwari, also known as Bhavartha Deepika, and the beautiful eleventh Skandha of the Bhagavat, which is referred to as Nath’s platform for the highest spiritual goal. These books were considered divinely inspired, and it was believed that those who perform the reading with faith attain God instantly. The instruction in the Bhagavat was considered the loving speech of Nath.
