What were the main religious books that Sai Baba encouraged his devotees to read in Shirdi?

Sai Baba placed great importance on the reading of specific, divinely inspired books for the spiritual welfare of his devotees. According to Chapter 18, the primary texts were the 'Jnaneshwari', which is also called 'Bhavartha Deepika', and the 'Nath Bhagawat', which is the eleventh Skandha of the Bhagavat. The 'Uddhava Gita' is also highlighted as a book that brings one to God instantly when read with faith. Baba assigned devotees like Sakharam Hari Jog to read these books daily in Sathe’s Wada, creating an opportunity of great use for all who came to Shirdi.
