What specific text did the Patil use for his 'Satya-Sai vow,' and what is its significance?

The text used by the Patil for his 'Satya-Sai vow' was the 'modern Bhaktalilamrut,' a work written by Das Ganu. As detailed in Chapter 13, this book contains forty-five chapters singing the praises of many devotees, but the Patil specifically focused on the three chapters that described the character of Sainath. He considered these three chapters to be the 'Satya-Sai story' itself, making them the centerpiece of his new devotional practice. By reading these chapters with love every Thursday, the Patil found boundless happiness and peace of mind. This choice highlights his personal connection to Sai and his desire to focus his worship directly on Sai's life and deeds.
