Can you explain the 'great wonder' that listeners experienced when Baba sent them to hear the book readings in the Wada?

A truly remarkable phenomenon often occurred, which Chapter 18 describes as a "great wonder" for the listeners. Sai Baba would sometimes tell a devotee a short story while they were with Him in the Masjid. Immediately after, He would instruct them to go to the Wada where Bapusaheb Jog was conducting his daily reading. Upon arriving, the devotee would be astonished to find that the portion of the sacred text being read at that very moment contained the exact same story Baba had just told them. This experience provided profound confirmation and a deeper understanding of Baba's story, making it seem as if Eknath's or Jnaneshwar's words were merely a translation of Baba's own speech. This demonstrated Baba's omniscience and His unique method of teaching.
