After being cured, what new tradition did the Patil start to show his gratitude to Sai Baba, and what did it involve?

As Chapter 13 describes, the Patil was filled with immense gratitude for Sai Baba's grace after his miraculous healing. To express this, he initiated a new tradition called the "Satya-Sai vow," which was modeled after the Satyanarayan vow. The Patil began to perform this vow regularly every Thursday. Instead of the traditional Satyanarayan story, his ritual involved reading the three chapters about Sainath from the "modern Bhaktalilamrut" written by Das Ganu. This practice, born out of the Patil's deep devotion and gratitude, eventually became a custom in his village.
