How does the tradition of creating and studying biographies like the Shri Sai Satcharita contribute to the community of Sai's followers?

The tradition of writing and reading biographies is a significant form of service that a Sadguru accepts from devotees, which in turn strengthens the community. Chapter 0 explains that a Sadguru can take service in two primary ways: by creating great works themselves or by having their biographies written by devotees. These biographies, such as the Shri Sai Satcharita by Annasaheb Dabholkar, are then used for study and Parayans by the wider congregation of devotees. This collective engagement with the Guru's life and teachings, as detailed in Chapter 0, helps devotees achieve their life's purpose and creates a shared spiritual foundation for the entire community.
