What devotional practice did Tatya Patil initiate out of gratitude to Sai Baba?

After being miraculously cured of a severe illness, Tatya Patil was filled with immense gratitude and initiated a new devotional practice called the "Satya-Sai vow." As described in Chapter 13, this was his unique way of showing continuous thanks. Similar to the traditional Satyanarayan vow, Patil would observe this on Thursdays. Instead of the usual story, he would lovingly read the three chapters about Sainath from the "Bhaktalilamrut" written by Das Ganu. This practice, complete with offerings and celebrations, became a regular custom in his village, demonstrating his deep faith and gratitude.
