Can you describe the 'Satya-Sai vow' that Chand Patil initiated?

The 'Satya-Sai vow' was a devotional practice started by Chand Patil to express his gratitude. According to Chapter 13, he modeled it after the traditional Satyanarayan vow. Every Thursday, after bathing, Patil would read specific chapters from a book by Das Ganu called the 'Bhaktalilamrut.' The three chapters that sang of Sainath's character became what he called the 'Satya-Sai story.' He performed this vow regularly with offerings (Naivedya) and celebrations, equating Sai with Narayan. This practice brought him boundless happiness and peace, eventually becoming a custom in his village.
