How can devotees serve Sai Baba and build a community around his teachings?

According to the preface in Chapter 0, one of the primary ways a Sadguru accepts service from devotees is through books. A community can be fostered through the collective study and devotional reading, known as Parayans or Saptahs, of a detailed biography. When devotees study and perform Parayans of a Guru's biography, it is considered a form of Guru service. Chapter 0 states that this shared practice allows devotees to achieve the purpose of their lives and is also seen as a form of public service and serving God in humanity (Jan-Janardan). The Shri Sai Satcharita is specifically identified as a detailed work suitable for this purpose.
