I want to organize a group reading of Sai Baba's life story. Are there specific texts recommended for this kind of community activity?

Yes, the text provides excellent guidance on this. While some works by poets like Shri Dasganu Maharaj mention Sai Baba, they are often not comprehensive enough for a detailed group study or Parayan. For a more in-depth community practice, the preface in Chapter 0 highly recommends the 'Shri Sai Satcharita'. This work, written by the devotee Shri Govind Raghunath alias Annasaheb Dabholkar, is described as a sweet, inspirational, and grace-filled biography specifically about Shri Sachidanand Samarth Sadguru Sai Baba Maharaj. It is considered one of the few detailed, poetic, and comprehensive works suitable for Parayans and Saptahs, making it ideal for your group reading.
