How did Sai Baba orchestrate teachings for his devotees using book readings in the Wada?

According to Chapter 18, Sai Baba employed a profound method for instructing his devotees. He assigned Bapusaheb Jog the task of reading sacred books like the Jnaneshwari and Nath Bhagawat daily in Sathe's Wada. Baba would then send devotees who came to visit him to go and listen to these readings. In a process described as a 'great wonder', Baba would often tell a devotee a short story, and when that person went to the Wada, they would find that the exact same story was being read from the book. This served as a powerful confirmation and provided a full understanding of Baba's lesson, making it seem as if the scriptures were a direct translation of his words.
