How did Baba use the scripture readings in the Wada to mystically confirm his own teachings to listeners?

Sai Baba employed a wondrous technique to reinforce his teachings and demonstrate his omniscience. As described in Chapter 18, He would sometimes tell a devotee a short story at the Masjid. While the devotee was still pondering its meaning, Baba would instruct them to "go to the Wada for that book." Upon arriving at the reading, the sincere listener would find that the portion of the Jnaneshwari or Nath Bhagawat being read at that very moment contained the exact same story Baba had just told. Chapter 18 notes that the scripture would seem to be a direct translation of Baba's story, providing powerful confirmation and a full understanding of the lesson, leaving the listeners in awe.
