How did a Patil's experience with a dream and subsequent healing in Chapter 13 demonstrate the power of faith and surrender to Sai?

The Patil's story in Chapter 13 powerfully illustrates the connection between faith, surrender, and divine grace. He experienced a strange and violent dream where a teacher beat him and a gentleman used a grinding stone on his chest, causing him immense agony. The text notes that while dreams are often considered illusions, in this case, the opposite was true. Upon waking, the Patil found his disease had vanished completely, and he felt reborn. This miraculous cure filled him with overwhelming joy and gratitude. As described in Chapter 13, he went for Baba's darshan and, recognizing the favor, placed his head at Sai's feet in total surrender. He understood that the painful dream was a beneficial act of grace and that complete surrender was the only appropriate response to Sai's unfathomable ways.
