How did Sai Baba use the book readings in the Wada to create profound experiences for his devotees?

The text in Chapter 18 reveals a fascinating method Sai Baba employed to bestow grace. He would sometimes tell a devotee a short story and then, while they were still contemplating it, instruct them to go to Sathe's Wada for the book reading. In what the text calls a "great wonder," the sincere listener would arrive to find that the exact same story they had just heard from Baba would come up in the portion of the book being read by Jog. This served as a powerful confirmation and provided a deeper understanding of Baba's initial story, making it seem as if Jnaneshwar’s or Eknath’s writings were a direct translation of Baba's own words.
