What are some established spiritual practices mentioned in the preface that can help build a community of Sai devotees?

A primary way to foster a community around Sai Baba's teachings is through the devotional practice of Parayan or Saptah, which involves the dedicated reading of a Guru's biography. As Chapter 0 explains, when devotees study and perform Parayans, the writer gains merit for serving God in humanity, and the participating devotees also progress toward their life's purpose. The text specifically highlights Annasaheb Dabholkar's Shri Sai Satcharita as the ideal, detailed work for such community-oriented devotional study concerning Shri Sai Baba Maharaj. This shared practice is a form of service to both the Guru and the congregation of devotees.
