According to Chapter 13, what are the essential qualities of a devotee that Sainath values, and how did the Patil embody them?

Chapter 13 explicitly states what Sainath requires from his followers: "Two hands, one head, stability, faith, and total surrender. Sainath needs nothing else; only that one gratitude should be there." The Patil is presented as a perfect example of these values. After his miraculous cure, his primary response was not a grand material offering but an overwhelming sense of gratitude. He demonstrated total surrender and faith by placing his head on Baba's feet, acknowledging that this was the only way he could possibly repay the favor. His subsequent actions, like instituting the 'Satya-Sai vow,' were born from a heart filled with gratitude, showing that sincere devotion and thankfulness are the true currencies of faith that Sainath values.
