What was the 'great wonder' that listeners often experienced when Baba sent them to the book readings in the Wada?

The 'great wonder' described in Chapter 18 was the incredible synchronicity between what Baba said and what was being read in the books. Often, Baba would tell a devotee a short story at the Masjid and then immediately instruct them to go listen to the reading at the Wada. When the sincere listener arrived, they would find that the exact same story or a related concept was being read from the book at that very moment. This provided the listener with powerful confirmation and a full, deeper understanding of Baba's initial story, making it seem as if the sacred texts were a direct translation of Baba's own words.
