How does the Patil's experience with the dreams in Chapter 13 illustrate the unconventional nature of Sai Baba's grace?

The Patil's story in Chapter 13 highlights that Sai Baba's grace is often "inconceivable and unfathomable." Instead of a conventional cure, Baba used two distressing dreams—one of a teacher with a cane and another of a grinding stone on the Patil's chest—to heal his disease. This demonstrates that Baba's methods operate beyond normal human understanding. The chapter points out that while dreams are typically seen as illusions, they can manifest a tangible, positive reality under Baba's influence, leading to the "destruction of the disease and relief from sorrow." This illustrates that compassionate saints like Sai can work in mysterious ways, removing worldly entanglements and even appearing to turn back time through their divine power.
