What were the paradoxical dreams the Patil had in Chapter 13, and how did these seemingly negative experiences lead to a positive outcome?

The Patil's healing came through two very strange and distressing dreams, as recounted in Chapter 13. In the first dream, a teacher beat him with a cane for failing to memorize a verse. Immediately following this, he had a second dream where a gentleman sat on his chest and used a grinding stone on it like a mortar, causing him immense agony. However, Chapter 13 clarifies the paradoxical nature of this event. Upon waking, the Patil's disease was completely gone. He realized that the 'punishment by the cane and the bursting of the heart' had a 'clearly beneficial' result, leading to the destruction of his illness and relief from sorrow, demonstrating how Sai's grace can work in mysterious ways.
