How did the Patil express his gratitude towards Sai Baba after being cured of his disease in Chapter 13?

After his miraculous cure, the Patil's gratitude was immense and expressed in several ways, as detailed in Chapter 13. He set out for Baba's darshan, and upon seeing Baba's face, his own "ocean of joy... became filled with the tide of bliss." He was overwhelmed with emotion, shedding floods of tears of love as he placed his forehead on Sai's feet. Recognizing the favor as a debt he could never repay, he declared that total surrender by placing his head at Sai's feet was his only settlement. Furthermore, he channeled this gratitude into a continuous form of worship by establishing and regularly performing the 'Satya-Sai vow' in his village.
