Can you explain the 'Satya-Sai vow' mentioned in Chapter 13 and how it compares to the Satyanarayan vow?

The 'Satya-Sai vow' was a devotional practice started by the Patil to express his gratitude for being healed. Chapter 13 draws a direct comparison to the well-known Satyanarayan vow, which people undertook to overcome a crisis. The Patil adapted this concept to honor Sai Baba. Instead of reading the Satyanarayan story, the Patil would read the three chapters dedicated to Sainath from Das Ganu's 'Bhaktalilamrut.' The text emphasizes the equivalence of the deities, stating, 'There it is Narayan, here it is Sai; there is no difference in either.' The Patil performed this vow regularly with offerings and celebrations, establishing a new tradition in his village.
