Based on Chapter 13, what does Sainath require from his devotees, and how did the Patil exemplify this?

Chapter 13 makes it very clear what Sainath requires from his followers. The source states, '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 the perfect embodiment of these qualities. After being miraculously healed, he was filled with an overflowing sense of gratitude and devotion. He approached Baba, placed his forehead on his feet, and acknowledged that total surrender was the only way to repay the favor. Furthermore, he channeled his gratitude into a continuous act of devotion by creating and regularly performing the 'Satya-Sai vow,' demonstrating his stable faith.
