How did Tatya Patil's perspective on devotion evolve after his miraculous cure by Sai Baba?

Following his miraculous healing, Tatya Patil's devotion transformed into one of profound gratitude and complete surrender. According to Chapter 13, upon seeing Baba after his recovery, he was flooded with tears of love and placed his forehead on Sai's feet, acknowledging the immense favor. He felt that simply placing his head at Baba's feet was the only way to settle his debt of gratitude. This sentiment is reinforced by the text which states, "Sainath needs nothing else; only that one gratitude should be there." His subsequent creation of the Satya-Sai vow was a tangible, lifelong expression of this deep-seated gratitude and surrender.
