The source text mentions 'punishment by the cane' and a 'grinding stone.' Were these real events or something else, and what was their purpose according to Chapter 13?

Chapter 13 clarifies that these events were not real in the physical sense but occurred in two vivid dreams the Patil had. In one dream, a teacher broke his back with a cane, and in the second, a man used a grinding stone on his chest. While the text notes that people often call dreams illusions, in this case, they manifested a healing reality. The purpose of this dream-suffering was ultimately benevolent. The text states, 'The punishment by the cane and the bursting of the heart—the result was clearly beneficial.' Upon waking, the Patil's disease was gone, showing the ordeal was a form of grace that brought about his recovery.
