What specific text did the Patil read for his 'Satya-Sai vow,' and why was it significant according to Chapter 13?

According to Chapter 13, the Patil began reading the 'modern Bhaktalilamrut' written by Das Ganu. This book was significant because it contained many stories of devotees, including three specific chapters dedicated to Sainath. The Patil considered these three chapters to be the 'Satya-Sai story' itself, viewing it as 'the best among all vows.' By reading these chapters with love and devotion, he obtained boundless happiness and peace of mind. The practice highlights a shift from a traditional ritual to a more personal one focused on reading and reflecting on the life and grace of Sai Baba as chronicled by a contemporary devotee.
