How can books about Sai Baba be used to build a community among his followers?

According to the preface of the Shri Sai Satcharita, a Sadguru accepts service from devotees through books. One key way this happens is when devotees write detailed biographies, which are then studied by the wider community. As Chapter 0 explains, when devotees study and perform 'Parayans' (devotional readings) of a work like the Shri Sai Satcharita, the writer gains the merit of serving God in humanity (Jan-Janardan), and the devotees participating also achieve the purpose of their lives. This shared practice of study and devotion forms a strong foundation for a spiritual community.
