Based on the Patil's story in Chapter 13, what does Sai Baba require from his devotees?

The Patil's story in Chapter 13 clearly outlines what Sainath desires from his followers. After being miraculously healed by Baba through a strange dream, the Patil felt an overwhelming sense of gratitude and realized he could never truly repay the favor. His response was one of complete submission, as he concluded, 'I only place my head at your feet. By this alone is my settlement.' The text then explicitly states what is needed: 'Two hands, one head, stability, faith, and total surrender. Sainath needs nothing else; only that one gratitude should be there.' Therefore, as demonstrated by the Patil's actions and the direct explanation found in Chapter 13, the essential requirements for a devotee are unwavering faith, profound gratitude, and total, unconditional surrender to Sai.
