How was the Patil's disease cured according to the events described in Chapter 13?

The Patil's healing was a miraculous event detailed in Chapter 13. He experienced two strange and violent dreams. In the second, a gentleman pressed a grinding stone on his chest, causing immense agony. Upon waking, the Patil found that his disease had vanished completely, and he felt an unprecedented freshness in his mind. As Chapter 13 explains, although dreams are often considered illusions, in this case, the dream led to the very real destruction of his disease and relief from sorrow. He felt as though he had been reborn and was overcome with gratitude for Sai Baba's grace.
