Can you explain the 'great wonder' that devotees experienced when Baba sent them from the Masjid to the readings at the Wada?

A remarkable and wondrous phenomenon often occurred, which is described in Chapter 18. Sai Baba would sometimes tell a short story to a devotee in the Masjid and then, while they were still absorbing it, he would instruct them to go to Sathe's Wada to listen to the sacred reading being conducted by Jog. The 'great wonder' for the listeners was that upon arriving at the Wada, the very same story Baba had just told them would come up in the portion of the book being read at that moment. This provided powerful confirmation and a much deeper understanding of Baba's teaching, making it seem as if the ancient words of Jnaneshwar or Eknath were a direct translation of Baba's own story, demonstrating his profound unity with the scriptures.
