What was the 'great wonder' that devotees often experienced when they were sent by Baba to listen to the readings at the Wada?

The 'great wonder' described in Chapter 18 was a form of miraculous synchronicity orchestrated by Sai Baba. After telling a devotee a short story at the Masjid, Baba would instruct them to go listen to the reading at the Wada. Upon arriving, the sincere listener would discover that the very same story or teaching was being read from the Jnaneshwari or Nath Bhagawat at that exact moment. This experience provided powerful confirmation of Baba's lesson and a deeper understanding, making it seem as though the ancient texts were a direct translation of Baba's own words.
