Based on the Patil's story in Chapter 13, what does Sainath truly require from his followers?

The story of the Patil in Chapter 13 provides a clear lesson on what Sainath values in his devotees. After being healed, the Patil was overwhelmed with gratitude and felt he could never repay the favor, simply placing his head at Baba's feet. The text explicitly states that Sainath doesn't need material offerings but rather a specific inner disposition. As mentioned in Chapter 13, "Two hands, one head, stability, faith, and total surrender. Sainath needs nothing else; only that one gratitude should be there." The Patil's subsequent actions, like starting the Satya-Sai vow, were an outward expression of this inner state of faith, surrender, and gratitude.
