What specific text did Tatya Patil read during his "Satya-Sai vow," and why was it considered the perfect choice?

For his unique "Satya-Sai vow," Tatya Patil used a specific modern text instead of a traditional one. As detailed in Chapter 13, he would read from the "Bhaktalilamrut," a work written by Das Ganu. This book contained forty-five chapters, but Patil focused on the three chapters that sang of Sainath's life and devotees. These three chapters were considered, in essence, the "Satya-Sai story" itself and the "best among all vows." This choice was perfect because it allowed him to focus his devotion directly on Sai Baba, the source of his miraculous cure, bringing him boundless happiness and peace of mind.
