What does Chapter 13 say Sainath truly requires from his devotees, as exemplified by the Patil's transformation?

The story of the Patil in Chapter 13 serves as a clear illustration of the core requirements for a devotee of Sainath. After his miraculous healing, the Patil is filled with gratitude and wonders how he can repay the favor. The narrative explicitly states what Sainath values most: "Two hands, one head, stability, faith, and total surrender. Sainath needs nothing else; only that one gratitude should be there." The Patil embodies this completely. He travels for Baba's darshan, places his forehead on Baba's feet in surrender, and establishes the Satya-Sai vow as a continuous act of gratitude. As Chapter 13 emphasizes, this complete surrender and unwavering faith are the only "settlement" or payment required.
