According to the events in Chapter 13, what qualities does Sainath value most in a devotee?

Chapter 13 highlights that what Sainath truly desires from his followers is not material wealth but sincere devotion. The text explicitly states, 'Two hands, one head, stability, faith, and total surrender. Sainath needs nothing else; only that one gratitude should be there.' The Patil perfectly embodied these qualities after his healing. He surrendered by placing his head at Baba's feet, acknowledging he could never fully repay the favor. His subsequent actions, like creating the Satya-Sai vow, were born from this profound sense of gratitude and faith, which are the core requirements mentioned.
