I want to organize a study group for Sai Baba's teachings. According to the texts, what kind of book is most suitable for this, and why?

For organizing a study group or performing a 'Parayan' or 'Saptah,' it is crucial to select a comprehensive and detailed work. Chapter 0 highlights that some biographies, like those by Shri Dasganu Maharaj, are not ideal for this specific purpose because they are not comprehensive, often spanning only a few pages. The text recommends detailed, poetic, and grace-filled biographies suitable for deep study. A prime example given for Sai Baba is the 'Shri Sai Satcharita' by Annasaheb Dabholkar. Choosing such a detailed work ensures that the study group has substantial material for devotional reading.
