What does Chapter 13 suggest Sai Baba truly desires from his devotees, and how is this illustrated through the Patil's story?

Chapter 13 reveals what Sainath truly values in his followers. The text explicitly states, 'Sainath needs nothing else; only that one gratitude should be there,' followed by a list of qualities: 'Two hands, one head, stability, faith, and total surrender.' This indicates that sincere devotion is far more important than material offerings or complex rituals. The Patil's story perfectly illustrates this principle. His response to being healed wasn't a grand material offering but an overwhelming feeling of gratitude that led him to surrender completely at Sai's feet and establish the 'Satya-Sai vow,' a practice rooted in love and remembrance rather than transaction.
