According to Chapter 13, what specific text did the Patil read as part of his 'Satya-Sai vow'?

Chapter 13 provides specific details about the devotional reading material used by the Patil for his 'Satya-Sai vow.' The text specifies that the Patil began to read the 'modern Bhaktalilamrut,' a work written by Das Ganu. This book was comprised of forty-five chapters in total. For his vow, the Patil would focus on the three specific chapters within that book that sang about Sainath. As Chapter 13 explains, the Patil considered these three chapters to be the 'Satya-Sai story' itself, and reading them brought him 'boundless happiness' and peace of mind. This practice of reading Das Ganu's work became the cornerstone of the vow he established.
