Can you describe the specific practices involved in the 'Satya-Sai vow' that the Patil initiated in Chapter 13?

The 'Satya-Sai vow' was a devotional tradition started by the Patil out of gratitude for his healing. As described in Chapter 13, the Patil began to perform this vow every Thursday. The practice involved bathing and then, instead of reading the traditional Satyanarayan story, he would read the three chapters dedicated to Sainath from the 'modern Bhaktalilamrut' written by Das Ganu. He would perform this vow regularly with a joyful mind, alongside friends, relatives, and brothers, with the same abundance of offerings and celebration as a traditional vow. For him, there was no difference between Narayan and Sai, and this practice brought him 'boundless happiness' and peace of mind.
