Beyond the plank incident, what other examples of Maharaj's supernatural insight are given in the book's introduction?

The introduction in Chapter 0 provides several instances of Maharaj's divine abilities. It mentions that Gopalrao Gund, who had three wives, was blessed with a son through Maharaj's grace. Furthermore, Maharaj demonstrated profound insight by revealing the existence of a hidden tomb. He stated that a Pir's tomb was located under a Neem tree near the village boundary, and upon digging, a tomb was indeed found. He also displayed foresight by preventing Gopalrao Gund from rebuilding the Masjid, noting the work was for someone else, and instead directing the resources to benefit other temples in the village.
