Can you describe the specific ritual of the 'Satya-Sai vow' that the Patil established, as mentioned in Chapter 13?

The 'Satya-Sai vow,' as described in Chapter 13, was a devotional ritual created by the Patil out of gratitude for his healing. He adapted the existing Satyanarayan vow to focus entirely on Sai Baba. The Patil would perform this vow "always on every Thursday, staying in the state of the vow after bathing." The central part of the ritual was the reading of sacred texts. Instead of the traditional Satyanarayan story, the Patil would read from the 'modern Bhaktalilamrut' written by Das Ganu. Specifically, he would lovingly read the three chapters within that work that sang of Sainath's character. He considered these chapters to be the "Satya-Sai story" and the "best among all vows." The practice was also accompanied by the "same abundance of offering (Naivedya) and the same auspicious celebration" as its traditional counterpart, establishing a new custom in his village.
