How were the Patil's dreams in Chapter 13 instrumental in his healing and change of heart?

In Chapter 13, the Patil experienced two very strange and distressing dreams. In the first, a teacher was punishing a student with a cane, and in the second, a gentleman sat on his chest and used a grinding stone on it like a mortar. Despite the agony, the Patil woke up to find that his disease had vanished and he felt an unprecedented freshness. The narrative explains that these dream experiences, which seemed like punishments, were actually the cause of his healing. As the text states, "At that very moment came the destruction of the disease and relief from sorrow for the Patil." This miraculous cure, stemming from what felt like an ordeal, led him to recognize Baba's profound and unconventional grace, filling him with immense gratitude.
