What specific devotional practices involving texts are recommended for building a community around Sai Baba, and which text is most suitable?

The source material suggests that performing a Parayan or Saptah (a week-long devotional reading) of a Guru's biography is a powerful way to build community. Chapter 0 explains that a Sadguru takes service from devotees by having his biographies written for the congregation to study. While some early works exist, the most suitable text for Sai Baba's followers is the 'Shri Sai Satcharita'. This grace-filled biography, written by Annasaheb Dabholkar, is described as detailed, poetic, and comprehensive, making it ideal for group study and Parayans, which in turn fosters a shared spiritual purpose among devotees.
