How does Chapter 13 contrast the painful experience of the Patil's dreams with their beneficial outcome?

Chapter 13 presents a fascinating paradox regarding the Patil's healing. His dreams were filled with agony: being beaten with a cane by a teacher and having his chest ground by a stone, causing his 'life to come up to his throat in agony.' However, the text explicitly states that 'the punishment by the cane and the bursting of the heart—the result was clearly beneficial.' Upon waking, the Patil was not only free of his disease but also felt an 'unprecedented freshness.' The narrative emphasizes this contrast, showing how Sai Baba's 'inconceivable and unfathomable' methods can use apparent suffering to bring about profound relief and spiritual benefit.
