Based on the Patil's experience in Chapter 13, what is the relationship between suffering, dreams, and divine grace?

Chapter 13 presents a complex relationship between suffering, dreams, and grace through the Patil's story. His healing comes only after he endures two violent and terrifying dreams, one of a caning and another of his chest being ground by a stone. The text explicitly states, 'The punishment by the cane and the bursting of the heart—the result was clearly beneficial.' This suggests that what appears as suffering can be a direct instrument of Sai's grace, an unconventional method for healing. Furthermore, the chapter challenges the idea that dreams are mere illusions, showing how they can manifest a tangible 'opposite reality' of healing and relief from sorrow, illustrating the 'inconceivable and unfathomable' novelty of Sai's methods.
