How did Sai Baba use the book readings in the Wada to demonstrate his divine knowledge to devotees?

Sai Baba had a remarkable way of connecting his personal interactions with the ongoing scriptural readings. As described in Chapter 18, he would sometimes tell a devotee a short story in the Masjid. Then, he would immediately instruct that person to go to Sathe's Wada to listen to the book reading. To the devotee's astonishment, they would find that Bapusaheb Jog was reading the very same story from the text. This provided profound confirmation of Baba's omniscience and made the listeners feel as though Jnaneshwar's or Eknath's words were merely a translation of Baba's own teachings, creating a sense of wonder.
