How does the study of Sai Baba's biography help in building a community of devotees?

The study of a detailed Guru biography is a powerful form of service that builds a strong community. As mentioned in Chapter 0, when devotees study and perform Parayans (devotional readings), the writer of the biography gains the merit of serving God in humanity, and the other devotees also achieve the purpose of their lives. The text explains that a Sadguru accepts service from his devotees through books, specifically by having his biographies written for a "congregation of devotees" to study. This shared act of study and devotion around a central text like the Shri Sai Satcharita naturally fosters a spiritual community.
