What happened to the Patil in Chapter 13 that strengthened his faith in Sai Baba?

Chapter 13 details a profound experience for a Patil who was suffering from a debilitating disease. He had two strange and painful dreams, one involving a teacher with a cane and another a gentleman using a grinding stone on his chest. As described in the chapter, when he awoke, his illness had completely vanished. He realized that the apparent 'punishment' in his dream was actually a form of Sai Baba's grace that had healed him. This miraculous event caused his faith to grow immensely, filling him with gratitude and leading him to place his head at Baba's feet in total surrender, acknowledging the unfathomable ways of Sai.
