Which specific sacred texts were central to the daily readings, and how are they described?

The source material in Chapter 18 identifies two main books: the Bhagavad Gita and the Bhagavat. The daily readings, led by Bapusaheb Jog, focused on specific commentaries and sections of these works. These included the commentary on the Gita known as Jnaneshwari or Bhavartha Deepika, and the eleventh Skandha of the Bhagavat, written by Eknath. These texts were considered the platform for achieving the highest spiritual goal, and Baba Himself showed great satisfaction when devotees engaged with them, indicating their profound importance.
