Who were the primary authors of the sacred books that Baba had read daily in Shirdi?

The two main authors whose works were read daily in Shirdi at Sai Baba's behest were Jnandeva and Eknath. Chapter 18 specifies their divinely inspired books as Jnandeva's commentary on the Gita, known as Jnaneshwari or Bhavartha Deepika, and the eleventh Skandha of the Bhagavat, referred to as Nath Bhagawat, which is Eknath's loving speech. The merciful Sainath made it a daily practice for these books to be read in Shirdi, with Sakharam Hari Jog often being the one to conduct the readings and provide explanations for the benefit of all devotees.
