How did Tatya Patil demonstrate his gratitude and service to Sai Baba after being cured of his illness?

After his miraculous cure, Tatya Patil expressed his profound gratitude through dedicated service and devotion. According to Chapter 13, he stayed in Shirdi for a month and then established a new form of worship called the "Satya-Sai vow." This was a practice he performed every Thursday, modeled after the Satyanarayan vow. Instead of the traditional story, Patil would read the three chapters about Sainath from Das Ganu's "Bhaktalilamrut." This act of devotion, which he performed with a joyful mind, became a regular custom for him, his family, and his village, serving as a testament to his unending faith and gratitude.
