Are there specific texts recommended for group study or 'Parayans' to build a community around Sai Baba?

Yes, the text explicitly recommends a specific work for this purpose. Chapter 0 mentions that while some poetic works exist, they are often not comprehensive enough for a detailed Parayan of a single saint. It then identifies the "Shri Sai Satcharita," written by the late devotee Shri Govind Raghunath alias Annasaheb Dabholkar, as the ideal text for Sai Baba devotees. This grace-filled biography is described as sweet and inspirational, making it perfectly suitable for Parayans and Saptahs. Engaging with this text is a primary method for a congregation of devotees to offer service and build community.
