What specific practices are mentioned that can help create a congregation of Sai devotees?

The texts suggest that a key practice for creating a congregation is the collective study and devotional reading, known as Parayan or Saptah, of a comprehensive Guru biography. Chapter 0 highlights that while some works exist, they are often not detailed enough for this purpose. However, it points to the "Shri Sai Satcharita" by Annasaheb Dabholkar as a sweet, inspirational, and grace-filled biography specifically suited for Parayans. By gathering to study and read this work, a congregation of devotees is formed, and the Sadguru accepts this as a form of service.
