Are there specific books recommended for building a community around Sai Baba's life story, and why are they special?

Yes, the text highlights a specific work as being particularly suitable for this purpose. While some earlier works by Shri Dasganu Maharaj exist, their biographies of individual saints are noted as not being comprehensive enough for detailed study. The text from Chapter 0 points to the Shri Sai Satcharita, written by Annasaheb Dabholkar, as a recent, sweet, inspirational, and grace-filled biography of Shri Sai Baba. It is considered one of only two such detailed, poetic, and comprehensive works in Maharashtra suitable for Parayans and Saptahs. Its detailed nature makes it an ideal text for devotees to gather around for study and devotional reading.
