Which specific books were considered most important for the daily readings, and what was their significance?

The source material in Chapter 18 identifies two main scriptures: the Bhagavad Gita and the Bhagavat, which are described as holding the essence of the Bhagavat religion. The specific texts used for the daily readings were the 'Jnaneshwari,' a renowned commentary on the Gita also known as 'Bhavartha Deepika,' and the eleventh Skandha of the Bhagavat written by Eknath. Baba placed immense importance on these readings, seeing them as a platform for attaining the highest spiritual goal and a crucial practice for the welfare of his devotees.
