How did Tatya Patil express his gratitude to Sai Baba after being miraculously cured of his illness?

After Sai Baba cured him, Tatya Patil was filled with immense gratitude and sought a way to express his devotion. As detailed in Chapter 13, he initiated a new tradition called the "Satya-Sai" vow. This practice was modeled on the Satyanarayan vow that people perform when in crisis. On every Thursday, Patil would devoutly read the three chapters about Sainath from the 'Bhaktalilamrut' written by Das Ganu. This act of regularly reading Sai's character and story, performed with a joyful mind, became his way of continually expressing his gratitude and faith, a tradition that eventually spread through his village.
