Could you describe the specifics of the 'Satya-Sai vow' that the Patil started? What did the ritual involve?

The 'Satya-Sai vow' was a tradition started by the Patil to show his continuous gratitude. According to Chapter 13, he began this practice after being healed by Baba. On every Thursday, the Patil would observe the vow after bathing. Instead of the traditional Satyanarayan story, he would read from the 'modern Bhaktalilamrut,' a work written by Das Ganu. Specifically, he would read the three chapters that sang of Sainath's character, which he considered to be the 'Satya-Sai story.' This practice brought him boundless happiness and peace of mind, and he would perform it with friends and relatives, establishing it as a village custom.
