What does Chapter 13 state that Sainath requires from his devotees, and how does the Patil's journey exemplify these qualities?

Chapter 13 explicitly states the requirements for a devotee of Sainath: 'Two hands, one head, stability, faith, and total surrender. Sainath needs nothing else; only that one gratitude should be there.' The Patil's story is a perfect illustration of these virtues. He demonstrated unwavering faith by accepting his terrifying dreams as a form of grace. His 'total surrender' is evident when he travels to Shirdi and places his head at Baba's feet, stating it is the only way he can repay the favor. Finally, his profound gratitude is the catalyst for his extended stay and the creation of the 'Satya-Sai vow,' a regular practice to honor Sai's compassion, thus embodying all the qualities Sainath desires.
